An investigator theorizes that people who participate in a regular program of exercise will have lower levels of anxiety than people who do not participate in a regular program of exercise. To test this idea the investigator randomly assigns 12 subjects to an exercise program for 10 weeks and 12 subjects to a non-exercise comparison group. Lower anxiety scores reflect lower levels of anxiety. Please test the investigator's theory using an alpha level of .05, two tailed.
