Question

Triglycerides are blood constituents that are thought to play a role in coronary artery disease. An experiment was conducted to

see if regular exercise could reduce triglyceride levels. Researchers measured the concentration of triglycerides in the blood serum

of seven male volunteers before and after participation in a 10-week exercise program. The results are shown below. Using the most

appropriate statistical test, does the study show that exercise significantly reduces triglyceride levels?

Person	Before	After
1	0.87	0.57

6	1.18	1.09
7	1.60	1.51
