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 5.1 and a standard deviation of 16.9. Construct a 90% confidence interval estimate of the mean net change in LDL cholesterol after the garlic treatment.

Question
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 5.1 and a standard
deviation of 16.9. 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 cholesterol?
