The following hypotheses are given:

H0 : σ1² − σ2² ≤ 0

H1 : σ1² − σ2² > 0

A random sample of twenty eight observations from the first population resulted in a standard deviation of 16. A random sample of four observations from the second population showed a standard deviation of 5. 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.)
