The changes​(beforeminus ​after) in their levels of LDL cholesterol​ (in mg/dL) have a mean of 5.1 and a standard deviation of 18.9. Construct a 95​% 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?
