Question 9 (2 points) The Centers for Disease Control and Prevention (CDC) reported that the mean cholesterol for adults over age 20 is 191 mg/dL. Suppose we conduct a test of significance on the effectiveness of 30 minute per day of weight lifting in lowering cholesterol levels. A random recruitment of adults that are at least 20- year old were randomly selected to participate in a four-week weight lifting activity of 30 minutes per day. The table below presents the statistics of cholesterol levels of 33 adults before and after as part of the study on weight lifting.
