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: s21s12 = 276, and n1 = 51
Sample 2: s22s22 = 164, and n2 = 26

a. Construct the 90% interval estimate for the ratio of the population variances. (Round "F" value and final answers to 2 decimal places.)


b. Using the confidence interval from Part (a), test if the ratio of the population variances differs from 1 at the 10% significance level.
