In a test of the effectiveness of garlic for lowering cholesterol, 44 44 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 3.6 3.6 and a standard deviation of 18.5 18.5. construct a 90 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 cholesterol?
