The changes (before-after) in their levels of LDL cholesterol (in mgid) have a mean of 4.1 and a standard deviation of 18.8. Construct a 90% confidence interval estimate of the mean net change in LDL cholesterol after the garlic treatment. What does the confidence interval suggest about the effectiveness of garlic in reducing LDL cholestero?
