In Exercises 2, test the given claim. Use a significance level of a = 0.05, and assume that all populations are normally distributed. Use the traditional method of testing hypotheses outlined, and draw the appropriate graphs.
Claim: Population A has a larger variance than population B.
Sample A: n = 50, x- = 77.4, s = 18.1
Sample B: n = 15, x-= 75.7, s = 7.0
