The following hypotheses are given:

H₀ : σ₁² − σ₂² ≤ 0

H₁ : σ₁² − σ₂² > 0

A random sample of thirty eight observations from the first population resulted in a standard deviation of 31. A random sample of thirty observations from the second population showed a standard deviation of 29. At the 0.05 significance level, is there more variation in the first population?

a. State the decision rule. (Round the final answer to 2 decimal places.)

Reject H₀ if F > .

b. Compute the value of the test statistic. (Round the final answer to 2 decimal places.)

Value of the test statistic

c. What is your decision regarding H_o?

(Click to select) Do not reject Reject
