In a test of the effectiveness of garlic for lowering​ cholesterol, 49 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 4.7 and a standard deviation of 16.4. 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? a) What is the confidence interval estimate of the population mean
