In a test of the effectiveness of garlic for lowering cholesterol, 43 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 mgldL) have a mean of 2.8 and a standard deviation of 16.8. Construct a 99% condence interval estimate of the mean net change in LDL cholesterol after the garlic treatment.
