A group of 60 volunteers who do not regularly exercise are randomly assigned to one of two fitness programs. One group of 30 is enrolled in a daily walking program, and the other group is put into a jogging program. After a period of 6 weeks, the two groups are compared based on their scores on a wellness index. What kind of a study is this? (Observational or experimental) If the study shows that the joggers score better than the walkers, is this association of cause-and-effect? Why?
