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.)
Value of the test statistic ???
