We want to examine the effectiveness of three programs on the weight loss of men and women in the 40-50 year old age range. 150 men and 150 women participate in the study. Subjects are randomly assigned to the three programs. They spend 3-4 hours in the program per week and they continue the program for six months. Their weight is recorded before and after the program. Choose the best answer.
Select one:
A. This is an experimental study because the subjects have been randomly assigned to different treatment groups
B. This study is a combination of experimental and observational because we are collecting data on both the experimental and the control group as well as talking to the people.
C. This is an experiment because the researcher is measuring the weight of the subjects before and after participation in the program
D. This is an observational study because the subjects may spend less time in the program than they are supposed to
