The gap between the earnings of men and women with equal education is narrowing but has not closed. Sample data for seven men and seven women with bachelor's degrees are as follows. Data are shown in thousands of dollars.

Men	Women
31.6	44.5
86.5	46.4
56.2	30.9
68.2	41.5
47.2	36.8
59.9	50.5
66.3	24.8

(a)

What is the median salary (in $) for men? For women?

(b)

Use ? = 0.05 and conduct the hypothesis test for identical population distributions.

State the null and alternative hypotheses.

- H
₀: The two populations of salaries are not identical.

H
_a: The two populations of salaries are identical

-
H
₀: Median salary for men − Median salary for women > 0

H
_a: Median salary for men − Median salary for women = 0

- H
₀: Median salary for men − Median salary for women ≥ 0

H
_a: Median salary for men − Median salary for women <>

- H
₀: The two populations of salaries are identical.

H
_a: The two populations of salaries are not identical.

- H
₀: Median salary for men − Median salary for women ≤ 0

H
_a: Median salary for men − Median salary for women > 0

* Find the value of the test statistic W and the
p-value. (Round your answer to four decimal places.)

c, What is your conclusion?

- Do not reject
H
₀. There is sufficient evidence to conclude that there is a significant difference between the annual salaries of men and women.

- Reject
H
₀. There is sufficient evidence to conclude that there is a significant difference between the annual salaries of men and women.

- Do not reject
H
₀. There is not sufficient evidence to conclude that there is a significant difference between the annual salaries of men and women.

- Reject
H
₀. There is not sufficient evidence to conclude that there is a significant difference between the annual salaries of men and women.
