In Problem 10.43, assume that two samples are selected from independent normally distributed populations.
a. At the 0.05 level of significance, is there evidence of a difference between σ21 and σ22?
b. Suppose that you want to perform a one-tail test. At the 0.05 level of significance, what is the upper-tail critical value of F to determine whether there is evidence that σ21 > σ22? What is your statistical decision?
