In a test of the effectiveness of garlic for lowering cholesterol, 49subjects 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 5.2 and a standard deviation of 17.2. 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? What is the confidence interval estimate of the population mean μ? ______mg/dL<μ<______mg/dL (Round to two decimal places as needed.)

In a test of the effectiveness of garlic for lowering cholesterol, 49subjects 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 5.2 and a standard deviation of 17.2. Construct a 90% confidenceinterval 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?
in their levels of LDL cholesterol (in mg/dL) have a mean of 5.2 and a standard deviation of 17.2. Construct a 90% confidence
What is the confidence interval estimate of the population mean μ?
______mg/dL<μ<______mg/dL (Round to two decimal places as needed.)
