Question
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 - after) in their levels of LDL cholesterol (in mg/dL) have a mean of 3.6 and a standard deviation of 17.9.

What is the confidence interval estimate of the population mean u?
O mg/dl <u<Omg/dL
(Round to two decimal places as needed.)
What does the confidence interval suggest about the effectiveness of the treatment?
O A. The confidence interval limits do not contain 0, suggesting that the garlic treatment did not affect the LDL cholesterol levels.
O B. The confidence interval limits contain 0, suggesting that the garlic treatment did affect the LDL cholesterol levels.
O C. The confidence interval limits contain 0, suggesting that the garlic treatment did not affect the LDL cholesterol levels.
O D. The confidence interval limits do not contain 0, suggesting that the garlic treatment did affect the LDL cholesterol levels.
