The PTA at Central High School is concerned that students who graduate from the school do not score well on mathematics achievement tests, on average, as to students from other schools in the district. The mean score for students in the larger school district is 98. The school principal randomly selects 15 students from the graduating class and administers the standardized mathematics achievement test. The scores of the 15 students from Central High are as follows:
105, 98, 101, 110, 96, 103, 104, 101, 98, 105, 112, 95, 105, 100, 108
(a) Formally state the hypothesis necessary to conduct a non-directional test.
(b) Complete the test at the 05 level of significance, and state your conclusions in English.
(c) Construct and interpret the 95% confidence interval around the sample mean.
(d) Compute the effect size Hedge's g

The standard deviation of the difference between the means of the two populations is
A) 12.9
B) 9.3
C) 4
D) 2
Answers
Answer: D) 2
Step-by-step explanation:
The standard deviation of the difference between the means of the two populations is given by:-
[tex]S.E.=\sqrt{\dfrac{\sigma^2_1}{n_1}+\dfrac{\sigma^2_2}{n_2}}}[/tex]
where [tex]n_1[/tex]= sample size of population 1
[tex]n_2[/tex]= sample size of population 2
[tex]\sigma^2_1[/tex]= variance of population 1
[tex]\sigma^2_2[/tex]= variance of population 2
As per given,
[tex]S.E.=\sqrt{\dfrac{112.5}{45}+\dfrac{54}{36}}}\\\\=\sqrt{4}\\=2[/tex]
Hence, the correct option is D) 2.

Compute z-score. Given ~ n(12,2.5),find z score when x =17
Answers
Answer:
The desired z-score is 2.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
n(12,2.5)
This means that [tex]\mu = 12, \sigma = 2.5[/tex]
z score when x =17
This is Z when X = 17. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{17 - 12}{2.5}[/tex]
[tex]Z = 2[/tex]
The desired z-score is 2.

The percent of the 7th grade students were in favor of wearing school uniforms is 42.9%.
From the given table,
7th grade students who are in favor of wearing uniform = 48
Total 7th graders = 112
So, the percent of the 7th grade students were in favor of wearing school uniforms
= 48 / 112 x 100
= 12 / 23 x 100
= 42.85%

4x - y = 8
6x + y = 2
--------------- +
10x = 10
x = 1
since x = 1, we can subtitute x to one of those equations
4x - y = 8
4(1) - y = 8
4 - 8 = y
y = 4 - 8
y = -4
x,y = 1,-4
Answer:
B is correct
Step-by-step explanation:
you add the two equations together. So 4x + 6x equals what? 10x. we know that y and -y cancel each other out. and then we all know that 8+2 is 10. now we have 10x=10 so x=1. We replace x for one and then we have 4 - y =8 so y has to equal -4 and there you have your answer, b

A building in a city has a rectangular base. The length of the base measures 70 ft less than twice the width. The perimeter of this base is 820 ft. What are the dimensions of the base?
Answers
Answer:
160 ft, 250ft
Step-by-step explanation:
Rectangular base:
Width = w
length =2w - 70
Perimeter = 820 ft
2*(length + width) = 820
2*(2w - 70 + w ) = 820
2 *(2w + w - 70) = 820 {Combine like terms}
2* (3w - 70) = 820
3w*2 - 70*2 = 820
6w - 140 = 820
6w = 820 + 140 {Add 140 to both side}
6w = 960 {Divide both sides by 6}
w = 960/6
w = 160 ft
length = 2*160 - 70
= 320 - 70
= 250 ft
