In a test of the effectiveness of garlic for lowering cholostorol, 45 subjects were treated with garlic in a processed tablet torm 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 3.4 and a standard deviation of 17.9 Construct a 90% confidence interval estimate of the mean not change in LDL cholesterol after the garlic treatment. What does the confidence interval suggest about the effectiveness of ganic in reducing LDL cholesterol? Click here to view at distribution table.
