Question 5 Thirteen MBA students joined a three-month fitness program because of high cholesterol. readings. Shown are the cholesterol readings of the 13 students before joining the three- month fitness program and right after the completion of the three-month fitness. program. The fitness trainer wants to test whether there is a drop in the cholesterol. readings for people who completed the three-month fitness program. Assume differences in cholesterol readings are normally distributed in the population.
