E Review Homework: Unit 3 - Homework 3 (Chapter 8-3) Question 6, 8.3.15-T HW Score: 75.54%, 10.58 of 14 points Close Points: 0.33 of 1 In a test of the effectiveness of garlic for lowering cholesterol, 64 subjects were treated with raw garlic. Cholesterol levels were measured before and after the treatment. The changes (before minus Question list K after) in their levels of LDL cholesterol (in mg/dL) have a mean of 0.9 and a standard deviation of 23.1. Use a 0.05 significance level to test the claim that with garlic treatment, the mean change in LDL cholesterol is greater than 0. What do the results suggest about the effectiveness of the garlic treatment? Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. Question 2 What are the null and alternative hypotheses?

Use the diastolic blood pressure measurements (in mm Hg) for adult females listed in the accompanying data table Question list K and test the claim that the adult female population has a mean diastolic blood pressure level less than 90 mm Hg. Suppose a diastolic blood pressure above 90 is considered to be hypertension. Use a 0.01 significance level. Based on the result, can we conclude that none of the adult females in the sample have hypertension? Question 2 Click the icon to view the data table.
