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 3.6 and a standard deviation of 17.7. Construct a 90% confidence interval estimate of the mean net change in LDL cholesterol after the garlic treatment. Click here to view at distribution table.

What is the confidence interval estimate of the population mean u? mg/dL <μ< mg/dL (Round to two decimal places as needed.) DE
