Question: Consider the following measures based on independently drawn samples from normally distributed populations: Sample 1: s21 = 220, and n1 = 20 Sample 2: s2

Consider the following measures based on independently drawn samples from normally distributed populations:
Sample 1: s21 = 220, and n1 = 20
Sample 2: s2 2 = 196, and n2 = 15
a. Construct the 95% interval estimate for the ratio of the population variances.
b. Using the confidence interval from part (a), test if the ratio of the population variances differs from one at the 5% significance level. Explain.
