In a test of the effectiveness of garlic for lowering cholesterol, 44 subjects were treated with garlic in a processed tablet form. Cholesterol levels were measured before and after the treatment. The changes
(before - after) in their levels of LDL cholesterol (in mg/dL) have a mean of 3.2 and a standard deviation of 15.4. 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?
