For women? $ men women $ (b) Use a = 0.05 and conduct the hypothesis test for identical population distributions. : State the null and alternative hypotheses. Ho: Median salary for men - Median salary for women > 0 Ha: Median salary for men – Median salary for women = 0 Ho: Median salary for men - Median salary for women so Ha: Median salary for men - Median salary for women > 0 Ho: The two populations of salaries are identical. Ha: The two populations of salaries are not identical. o Ho: The two populations of salaries are not identical. Ha: The two populations of salaries are identical. Ho: Median salary for men - Median salary for women > 0 Ha: Median salary for men – Median salary for women < 0 Find the value of the test statistic. W = Find the p-value. (Round your answer to four decimal places.) p-value = What is your conclusion? Do not reject Ho. There is sufficient evidence to conclude that there is a significant difference between the annual salaries of men and women. Reject Ho. There is sufficient evidence to conclude that there is a significant difference between the annual salaries of men and women. Reject Ho. There is not sufficient evidence to conclude that there is a significant difference between the annual salaries of men and women. Do not reject Ho.
