Suppose that scores for men on an aptitude test have greater variability than scores for women on the same test. In other words, the population standard deviation is greater for the population of men than for the population of women.

Based on a sample of size 50, a 95% confidence interval for the mean score, μ, of all women has a margin of error of 2.2.

Which of the following confidence intervals will have a margin of error smaller than this 2.2?
