Construct the 99% interval estimate for the ratio of the population variances using the following results from two independently drawn samples from normally distributed populations. (Round "F" value and final answers to 2 decimal places. You may find it useful to reference the appropriate table: chi-square table or F table)

Sample 1: x⎯⎯x¯ 1 = 165, s21s12 = 25.7, and n1 = 11

Sample 2: x⎯⎯x¯ 2 = 161.7, s22s22 = 22.1, and n2 = 10
