Question: Given two normal populations A and B, we are interested in finding if the population variances of the two populations are equal. We are given

Given two normal populations A and B, we are interested in finding if the population variances of the two populations are equal. We are given the following information.

Sample from population A Sample from population B

Sample standard deviation = 16 hoursSample standard deviation = 10 hours

Sample size = 25Sample size = 20

Determine if the two population variances are equal or not by using a two-tailed hypothesis test with a level of significance = 0.05.
