The charges ( before - after) in ther levels of LDL cholesterol (in my/dL) have a mean of 3.4 and a standard deviation of 15.3. Construct a 95%% confidence interval estimate of the mean net change in LDL cholesterol after the gallic weanmerit. What does the confidence interval suggest about the effectiveness of garlic in reducing LDL dhicilesterd? A. The confidence interval limits contain 0, suggesting fhell the garlic treatment did not affect the LDL cholesterol levels O B. The confidence interval limits do not contain 0, suggesting that the garlic treatment did affect the LDL cholesterol levels, C. The confidence interval limits contain 0, suggesting that the garlic treatment did affect the LDL cholesterol levels D.
