A researcher was interested in the impact of exercise on mental health. He recruited two groups of participants: 30 who engaged in an hour or more of aerobic exercise daily and 30 who did not engage in any aerobic exercise. He administered a valid mental health inventory to all and found lower scores (i. E., lower mental health) in the sedentary group. He concluded that exercise had a positive effect on mental health. How does this design either support or fail to support this conclusion? Be specific.

The way this design supports the conclusion is that there is a correlation between the exercise and the results of the test.
