question 11

Short Answer

The following are the measures based on independently drawn samples from normally distributed populations:
Sample 1: = 345,and n₁ = 25
Sample 2: = 276,and n₂ = 21
A)Construct a 90% interval estimate of the ratio of the population variances.
B)Test if the ratio of the population variances differs from 1,using the computed confidence interval,at the 10% significance level.
