Question: To assess to the relative happiness of men and women in their marriages, a marriage counselor plans to administer a test measuring happiness in marriage to n randomly selected married couples, record the their test scores, find the differences, and then draw inferences on the possible difference. Let μ₁ and μ₂ be the true average levels of happiness in marriage for men and women respectively as measured by this test. Suppose it is desired to find a 90% confidence interval for estimating μ_d = μ₁ - μ₂ to within two test points. Suppose further that, from prior studies, it is known that the standard deviation of the differences in test scores is σ_d ≈ 10. What is the minimum number of married couples that must be included in this study?
