Public Accountant	Financial Planner
49.2	48.0
58.8	49.2
56.3	53.1
59.2	56.9
55.2	51.9

50.9	48.7
60.5	53.9
56.0	52.8
52.9	47.9

(a)

Use a 0.05 level of significance and test the hypothesis that there is no difference between the starting annual salaries of public accountants and financial planners.

State the null and alternative hypotheses.

H₀: Median salary for public accountants − Median salary for financial planners ≤ 0
H_a: Median salary for public accountants − Median salary for financial planners > 0H₀: The two populations of salaries are identical.
H_a: The two populations of salaries are not identical.    H₀: Median salary for public accountants − Median salary for financial planners > 0
H_a: Median salary for public accountants − Median salary for financial planners = 0H₀: Median salary for public accountants − Median salary for financial planners ≥ 0
H_a: Median salary for public accountants − Median salary for financial planners < 0H₀: The two populations of salaries are not identical.
H_a: The two populations of salaries are identical.

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 H₀. There is not sufficient evidence to conclude that there is a significant difference between the starting annual salaries of public accountants and financial planners.Reject H₀.
