c. with a= 0.05, what is you hypothesis testing conclusion?


a. What is the value of the test statistic (round to 2 decimals)?

Answers

Answer 1

Answer:

To find the value of the test statistic, we need to calculate the standard error of the difference between the means and then use it to calculate the z-score.

The formula for the standard error of the difference between the means is:

SE = sqrt((s1^2/n1) + (s2^2/n2))

where s1 and s2 are the sample standard deviations, and n1 and n2 are the sample sizes.

Substituting the given values, we get:

SE = sqrt((5^2/45) + (6^2/55)) = 1.257

The formula for the z-score is:

z = (x1 - x2) / SE

Substituting the given values, we get:

z = (25.5 - 22.6) / 1.257 = 2.31

Therefore, the value of the test statistic is 2.31

B. $3,848,400

Answers

The depreciation charges if the property was sold in November 2013, given the cost of the shopping center, is B. $3,848,400.

How to find the depreciation charges ?

To determine the depreciation charges, we need to know the cost of the depreciable assets, the useful life of the shopping center, and the depreciation method used.

With the straight-line depreciation method, the annual depreciation expense is calculated by dividing the depreciable cost by the useful life:

Annual depreciation expense = (Depreciable cost) / (Useful life)

Annual depreciation expense = ($45M) / (39 years)

Annual depreciation expense = $1,153,846 per year

Total depreciation charges = $576,923 + $1,153,846 + $1,153,846 + $961,538

= $3,848,400

Shale Remodeling uses time and materials pricing. It reports the following information:

Direct labor rate $ 145 per DLH
Non-materials-related overhead $ 115 per DLH
Materials-related overhead 10% of direct materials cost
Target profit margin (both conversion and direct materials) 20%

What price should the company quote for a job requiring four direct labor hours and $580 in materials?

Answers

Shale Remodeling should quote a price of $2,013.60 for this job.

How to calculate the price

Direct materials cost = $580

Materials-related overhead cost = 10% x $580

Materials-related overhead cost = $58

Total cost = direct labor cost + non-materials-related overhead cost + direct materials cost + materials-related overhead cost

Total cost = $580 + $460 + $580 + $58

Total cost = $1,678

Target profit margin = 20% of the selling price

Target profit margin = 20% of (selling price - total cost)

We can rearrange this formula to solve for the selling price:

Selling price = (target profit margin + 1) x total cost

Selling price = (0.20 + 1) x $1,678

Selling price = $2,013.60

Therefore, Shale Remodeling should quote a price of $2,013.60 for this job.

You have decided to expand your business and will now value shares. Given the following information, what is the value of a share in AMS today using the following information. AMS Ltd will not pay any dividends for the next 7 years; In exactly 7 years from today, AMS Ltd will pay a dividend of $1.28; The following four dividends (years 8, 9, 10 and 11) will grow at a rate of 40% per year; The dividends from year 12 onwards will grow at a more sustainable rate of 3% per year in perpetuity (note: the year 12 dividend will be 3% higher than the year 11 dividend); and, Dividends are paid annually, and the required rate of return on equity is 6% p.a compounded annually.​

Answers

Answer:

To value the share of AMS Ltd, we need to calculate the present value of all future dividends and the future sale price of the share. Here are the steps to calculate the value of a share in AMS:

1. Calculate the present value of the 7th-year dividend:

PV(dividend in year 7) = $1.28 / (1 + 6%)^7 = $0.84

2. Calculate the present value of the dividends from years 8 to 11:

PV(dividends in years 8-11) = $1.28 * (1 + 40%) / (1 + 6%)^8 + $1.28 * (1 + 40%)^2 / (1 + 6%)^9 + $1.28 * (1 + 40%)^3 / (1 + 6%)^10 + $1.28 * (1 + 40%)^4 / (1 + 6%)^11

PV(dividends in years 8-11) = $4.98

3. Calculate the present value of the future dividends beyond year 11:

PV(future dividends) = $1.28 * (1 + 40%)^5 * (1 + 3%) / (6% - 3%) / (1 + 6%)^11

PV(future dividends) = $17.29

4. Calculate the present value of the future sale price of the share:

PV(future sale price) = $1.28 * (1 + 40%)^5 / (6% - 3%) / (1 + 6%)^11

PV(future sale price) = $44.79

5. Add up the present values of all future cash flows to get the total value of the share:

Value of a share in AMS = $0.84 + $4.98 + $17.29 + $44.79

Value of a share in AMS = $67.90

Therefore, the value of a share in AMS today is $67.90.

Principle of management
Inside MindTap, Chapter 2, are various "company videos". Go specifically to the company video "Barcelona Restaurants" and answer the following questions.

After answering the questions, please also comment on 2 other student postings. When you respond to other students do not say "I agree" or something simple. You are needing substantial commentary on their answers. Feel free to politely disagree, and enjoy the discussion between peers.

You are required to make a substantial post before being able to see other student postings. Do not post a "blank" or simple posting, with plans to later edit that posting (so you can see other student answers). It shows your instructor all of your original posts before editing, and you will earn a 0 on your assignment for doing that.

DISCUSSION QUESTIONS:

1. What did the entrepreneurs say about "brainpower" in the video? There was a comment by both managers involving "disagreement", and how many brains are involved in running their business. Summarize their feelings, and then state whether you agree or disagree with this. Why or why not? When it is more appropriate to have highly structured process and procedure in running a restaurant?

2. Have you ever experienced highly structured management styles? Did you like it, or not? For example, I (Todd, your instructor) managed a call center where agents were required to say, exactly, "Customer Service, this is Todd, may I have your account number please?" as their greeting. They were also required to say, verbatim, "Thank you for calling BankName, good-bye." If they varied from this structure, they were scored lower on their call ratings. This helped the bank show the same service to all customers, in the minds of the managers. We also had very specific ways to access the phone, take breaks, and so on. This is an example of high structure, and I am not saying it was good or bad. Do you have examples of "very high" or "very low" structure to share? Relate it to the video.

3. The manager in the video disagrees with a very common customer service philosophy. What does he say he disagrees with? Do you agree with his statement, why why not?

Topic

Answers

Answer:

1. In the video, the entrepreneurs emphasized the importance of brainpower and collaboration in running their businesses. They mentioned that they encourage disagreement and different perspectives to make better decisions. They also mentioned that they have a team of managers who work together to make decisions and solve problems. I agree with their approach as I believe that diverse perspectives and collaboration can lead to better decision-making and problem-solving. Highly structured processes and procedures may be more appropriate in running a restaurant when it comes to food safety, sanitation, and customer service standards.

2. Highly structured management styles can be beneficial in some situations, such as in industries where quality control and consistency are essential. In the case of the call center example provided by the instructor, having a standardized greeting and closing may help ensure that all customers receive the same level of service. However, too much structure can also stifle creativity and innovation, which can be detrimental to a business. In the case of the Barcelona Restaurants video, the entrepreneurs seem to strike a balance between structure and flexibility by encouraging collaboration and diverse perspectives.

3. The manager in the video disagrees with the common customer service philosophy of "the customer is always right." He argues that customers are not always right and that it is important to stand up for what you believe in as a business. While I understand his point of view, I believe that customer satisfaction should be a top priority for any business. However, this does not mean that customers are always right, but rather that their concerns and feedback should be taken seriously and addressed respectfully and professionally. In the end, a business needs to find a balance between meeting customer needs and standing by its values and principles.

Comment on other student postings:

1. I agree with the first student's response that highly structured processes and procedures may be more appropriate in areas such as food safety, sanitation, and customer service standards. However, I also believe that it is important to strike a balance between structure and flexibility to foster creativity and innovation. In the case of the Barcelona Restaurants video, the entrepreneurs seem to have found a good balance by encouraging collaboration and diverse perspectives.

2. I appreciate the second student's personal experience with highly structured management styles in a call center. While structure can be beneficial in some situations, it can also stifle creativity and innovation. In the case of the Barcelona Restaurants video, the entrepreneurs seem to have found a good balance by encouraging collaboration and diverse perspectives. Businesses need to find a balance between structure and flexibility to meet their goals and values.

I wedded in December 2010 and moved in with my husband who got an apartment somewhere in Suleja. I worked in a firm in Abuja and he (my husband) worked in Kaduna so he was not always around. By January 2011, I found out that I was already pregnant with my son. It was a joyful moment especially when I broke the news to my husband that he would soon be a father. All through the pregnancy, I could count how many times my husband came home. Most of the time he would come home, he would only spend the weekend and leave by either Sunday evening or Monday morning. I practically carried the pregnancy alone. I worked in a call Centre where we worked based on schedule; either a Morning shift or an Afternoon shift. I earned $3,000 per year. My cost of transportation was $500, feeding was $800, rent was $500, and utilities took $200. This would leave me with a savings of $1,000 that I could use to do any other activity that would satisfy me. All of a sudden, the city became unsafe to reside in. I love my job so I would pay $200 to do it. There was practically killing that would happen at some point. Needless to mention that whenever I was on morning duty, I would leave my house by 5 am just to beat the traffic. In all, I was unsettled. When I was a few months before my due date, my mother suggested that I come over to Enugu to deliver my son. I took a maternity leave and left for Enugu. I gave birth to my cute son who would soon be 12 years old. After I delivered my son, my husband got a job in Enugu and we were left to decide whether to resign from my job and relocate to Enugu. Mind you, it would cost us about $500 to move our properties to Enugu, rent an apartment which would cost about $600 then stay jobless for a while. However, I would have peace of mind because Enugu is more peaceful and I would have the opportunity to stay together with my husband. Therefore, I would pay $5,000 to have the latter. I was left with the decision of either going back to Abuja and continuing with my job with the unsettled nature of the city or staying back in Enugu and losing my job.

Calculate the following: Opportunity Cost – With each alternative you outline in your introduction, discuss the opportunity costs which come along with making those decisions. For instance, if you have alternatives A and B, discuss the opportunity costs of selecting A over B, and then discuss the opportunity costs of selecting B over A. Remember to always assign a dollar value to the level of enjoyment or other non-monetary elements of your decision-making.
Cost-Benefit Analysis – Prepare a cost-benefit analysis clearing showing in real dollars the results of this analysis for each alternative.

Answers

Opportunity cost: The opportunity cost of staying in Enugu is losing her job and the opportunity cost of going back to Abuja is the risk to her safety and the need to be apart from her husband.

Cost-Benefit Analysis:

Staying in Enugu:

Costs: Moving expenses ($500), rent ($600/month), loss of income ($3,000/year)Benefits: Living with husband (value: $5,000), peace of mind (value: $2,000)

Going back to Abuja:

Costs: Safety risk, separation from husband, cost of transportation ($500/month)Benefits: Income ($3,000/year)

Based on the cost-benefit analysis, staying in Enugu would be more beneficial as the benefits outweigh the costs. The total costs of staying in Enugu are $9,100 (moving expenses + rent + loss of income), while the total benefits are $7,000 (value of living with husband + peace of mind).

The net benefit of staying in Enugu is $1,900. On the other hand, the total costs of going back to Abuja are $6,000 (cost of transportation), while the total benefits are $3,000 (income). The net benefit of going back to Abuja is $-3,000, indicating that this option is not financially feasible.

Equipment brought at cost of $25,000 is being considered for depreciation accounting using
either the SOYD (sum-of-years-digit method) or SL (straight-line) method. If this asset will be depreciated over a period of 5 years with a salvage value of $5,000, determine the percentage increase in depreciation charges in year 2 for the SOYD method over the SL method.
A. 10%
B. 33%
C. 0%
D. -33.33%

Answers

The correct answer for the percentage is option B. 33%.

How did we get the value?

To calculate the depreciation charges using the straight-line method, we first need to determine the depreciable base, which is the cost of the equipment minus the salvage value. So, the depreciable base is:

Depreciable base = $25,000 - $5,000 = $20,000

Using the straight-line method, the depreciation expense for each year would be:

Depreciation expense = Depreciable base / Number of years

Depreciation expense = $20,000 / 5 = $4,000 per year

So, in year 2, the depreciation expense using the straight-line method would be $4,000.

Now, let's calculate the depreciation charges using the SOYD method. To do this, we need to calculate the sum of the years' digits for a 5-year period:

Sum of the years' digits = 1 + 2 + 3 + 4 + 5 = 15

The percentage of the depreciable base that will be depreciated in year n using the SOYD method is:

Percentage of depreciable base in year n = (Number of years left in useful life / Sum of the years' digits) * 100

So, the percentage of the depreciable base that will be depreciated in year 2 is:

Percentage of depreciable base in year 2 = (4 / 15) * 100 = 26.67%

Therefore, the depreciation expense in year 2 using the SOYD method would be:

Depreciation expense in year 2 = Depreciable base * Percentage of depreciable base in year 2

Depreciation expense in year 2 = $20,000 * 26.67% = $5,334

The percentage increase in depreciation charges in year 2 for the SOYD method over the SL method is:

Percentage increase = ((SOYD method depreciation expense in year 2 - SL method depreciation expense in year 2) / SL method depreciation expense in year 2) * 100

Percentage increase = (($5,334 - $4,000) / $4,000) * 100 = 33.35%

Therefore, the correct answer is B. 33%.

We can say that for each sample, we would calculate the proportion of defective items (i.e. divide the number of defectives by the sample size), and plot that proportion on the P chart.

How to calculate the control limits?

1) The control limits for the 3-sigma P chart can be calculated using the formula:

Upper control limit (UCL) = p + 3√( p(1- p)/n)

Lower control limit (LCL) = p - 3√( p(1- p)/n)

where p is the average proportion of defective items across all samples, and n is the sample size (in this case, n=200).

To find p, we first need to calculate the total number of defective items across all samples, which is: (10+15+12+9+7+11+8+13+16+10+18+6+12+14+17+9+11+8+13+16) = 212

Then, we divide this by the total number of items inspected across all samples (which is 20 x 200 = 4000) to get

p : p= 212/4000 = 0.053

Now we can substitute p and n into the UCL and LCL formulas:

UCL = 0.053 + 3√(0.053(1-0.053)/200) = 0.106

LCL = 0.053 - 3√(0.053(1-0.053)/200) = 0.000

Therefore, the control limits for the 3-sigma P chart are: UCL = 0.106

LCL = 0.0002)

The first two sample points (numerical values) in the chart would depend on which samples were taken first and second by the operator. Without that information, we cannot determine the specific values for the first two samples.

What is an example of lack of accurate and timely accounting information?

Answers

Some examples of lack of accurate and timely accounting information include:

• Outdated financial statements like income statements, balance sheets, cash flow statements, etc. that do not reflect the current financial position of the company.

• Delays in recording transactions which can lead to inaccurate accounting records. For example, invoices not recorded for weeks or months.

• Lack of periodic reconciliation of balance sheet accounts like accounts receivable, accounts payable, inventory, etc. This can result in inaccurate balances in the financial statements.

• Lack of budgeting and variance analysis to monitor key metrics and identify potential issues. Out of date or non-existent budgets provide no visibility into actual performance vs targets.

• Lack of reliable management information systems to aggregate data from different operational areas. Key metrics and KPIs cannot be tracked and monitored.

• Lack of audit trails to see the history of changes made to accounting records. This reduces transparency and increases the risk of fraud or manipulation.

• Decentralized and manual accounting processes that lead to delays, errors and redundancy. Lack of accounting automation results in low efficiency and high workload.

• Irregular or lack of management reviews of accounting information and financial statements. Important issues may go unnoticed for longer periods.

Those are some common examples of lack of accurate and timely accounting information in an organization. Let me know if you need more details.

Answers

Methods of data collection refer to the various techniques used to gather information for research or analysis.


What is Primary Data Collection?

Primary data collection involves collecting data firsthand through methods such as surveys, interviews, and observation. Secondary data collection involves using existing data sources such as published reports, government statistics, and other published data.

Methods of data presentation include frequency distribution, which involves organizing data into categories and displaying the number of observations in each category.

Other methods include bar charts, pie graphs, histograms, and frequency polygons, which are used to visually represent data and show patterns and relationships within the data.

Ungrouped and grouped frequency distributions are used to organize data into intervals, and histograms are used to display the data in a bar chart-like format. Frequency polygons are similar to histograms, but lines are used to connect the tops of each bar.

A US based MNC is considering establishing a three-year project in Canada with a US$60 million initial investment. The required rate of return on this project is 15%. The firm is projected to generate operating cash flows of C$20 million in Years 1 and 2, and C$50 million in Year 3, and is expected to have a salvage value of C$30million.
The MNC must pay a 25% tax on remitted funds, and the stable exchange rate is C$1.02 per US$ over the next two years and a rate of C$1.025 per US$ in year 3.
All cash flows are remitted to the parent and there is no tax on salvage.
Required:
i) Calculate the after-tax operating cash flows that will be remitted to the parent
company each year.
ii) Calculate the Net Present Value of the project.
iii) Explain whether or not the MNC should accept the project?
iv) Flagstaff Corp. is a U.S.-based firm with a subsidiary in Mexico. It plans to reinvest its earnings in Mexican government securities for the next 10 years since the interest rate earned on these securities is so high. Then, after 10 years, it will remit all accu- mulated earnings to the United States. What is a drawback of using this ap- proach? (Assume the securities have no default or interest rate risk.).

Answers

i) The after-tax operating cash flows that will be remitted to the parent company each year are US$11,925,000 in Year 1, US$11,925,000 in Year 2, and US$29,812,500 in Year 3.
ii) The Net Present Value of the project is US$21,256,000.
iii) The MNC should accept the project because the Net Present Value is positive.
iv) A drawback of using this approach is that the exchange rate may fluctuate over the 10-year period, which could result in a lower or higher return on investment when the earnings are remitted to the United States.

Which of the following best represents the pricing behavior of firms in a monopolistically competitive industry?

Answers

In a monopolistically competitive industry, firms demonstrate pricing behavior that is influenced by product differentiation and market power, allowing them to set prices above marginal cost and earn short-term profits. However, in the long run, increased competition from new entrants brings prices closer to the average total cost.

The pricing behavior of firms is best represented by price-setting based on product differentiation and market power. Firms in such industries have some degree of market power due to the uniqueness of their products, which allows them to set prices above marginal cost without losing all of their customers.

The key characteristics of monopolistic competition include:
1. A large number of firms: This ensures that each firm has a small share of the market, preventing any single firm from dominating the industry.
2. Product differentiation: Firms in this industry offer slightly different products, which allows them to differentiate themselves from their competitors and charge a premium price for their unique offerings.
3. Free entry and exit: New firms can easily enter the market, and existing firms can exit without significant barriers, ensuring a dynamic and competitive environment.

In a monopolistically competitive industry, firms set their prices based on the perceived value of their product rather than purely on cost. They can do this because their products are differentiated and consumers are willing to pay a higher price for the unique features that their products offer. This allows firms to earn a profit in the short run; however, in the long run, the entry of new firms erodes this profit as competition increases and prices are driven down to the point where they are closer to the average total cost.
