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?
