Exercise 11-26 Algo Consider the following measures based on independently drawn samples from normally distributed populations: (You may find it useful to reference the appropriate table: chi-square table or F table) Sample 1: 87 = 240, and n1 = 26 Sample 2: 85 = 221, and n2 = 16 a. Construct the 95% interval estimate for the ratio of the population variances. (Round "P' value and final answers to 2 decimal places.) Confidence interval to b. Using the confidence interval from Part (a), test if the ratio of the population variances differs from 1 at the 5% significance level. The 95% confidence interval contains the value 1. Thus, we cannot
