In a home improvement company, all female employees with 2 to 5 years of experience have a mean salary of $27300 with a with a variance of $30580900.A random sample of 30 male employees also having 2 to 5 years of experience had a mean salary of $23900.The company accountant hypothesizes that female employees make less money than male employees.What can be concluded with an?of 0.10?

a)What is the appropriate test statistic?

One-Sample t-test (This is the topic of the chapter)

b) Solve for the Population and Sample below:

Population= ---Select ONE of the following---

-salary

-the CEO

-male employees

-female employees

-home improvement company

Sample= ---Select ONE of the following---

-salary

-the CEO

-male employees

-female employees

-home improvement company

c)Obtain/compute the appropriate values to make a decision aboutH₀.

Critical Value = ______;

Test Statistic =_______ ;

Decision= (Reject H0 or Fail to reject H0).

d)If appropriate, compute the CI.If not appropriate, input "na" for both spaces below.

[_____,_____]

e)Compute the corresponding effect size(s) and indicate magnitude(s).

If not appropriate, input and select "na" below.

d=_____;

Magnitude= ---Select ONE of the following---

-na

-trivial effect

-small effect

-medium effect

-large effect

r²=_____;

Magnitude= ---Select ONE of the following---

-na

-trivial effect

-small effect

-medium effect

-large effect

f)Make an interpretation based on the results (WHICH OF THE FOLLOWING THREE STATEMENTS IS TRUE?):

-The salary of female employees is significantly lower than male employees.

-The salary of female employees is significantly higher than male employees.

-The salary of female employees did not differ from male employees.

Below is a picture of the question, for clarification. thank you!

Application Exercise: In a home improvement company, all female employees with 2 to 5 years of experience have a mean salary of $27300 with a with a variance of $30580900. A random sample of 30 male employees also having 2 to 5 years of experience had a mean salary of $23900. The company accountant hypothesizes that female employees make less money than male employees. What can be concluded with an a of 0.10? a) What is the appropriate test statistic? -Select-- v bj Population: -Select- Sample: -Select-- c) Obtain/compute the appropriate values to make a decision about H.
