STATS: In a test of the effectiveness of garlic for lowering cholesterol?
In a test of the effectiveness of garlic for lowering cholesterol, 47 subjects were treated with garlic in a processed tablet form. Cholesterol levels were measured before and after the treatment. The changes (before
minus−after) in their levels of LDL cholesterol (in mg/dL) have a mean of
4.6 and a standard deviation of 19.1. Construct a 95% 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 cholesterol?
