They then administer the drug to the participants, wait 30 minutes, and measure their cholesterol levels again. μ₁ represents the average cholesterol level before the drug, μ₂ represents the average cholesterol level after, and μ_d represents the average difference between before and after. Test at a significance level of .05.
