Question
2. 90 male volunteers are randomly assigned to three different treatment programs designed
to produce a weight loss by focusing on either diet, exercise, or the modification of eating
behaviour. Weight changes were recorded, to the nearest pound, for all participants who
completed the two-month experiment. Positive scores signify a weight drop; negative scores,
a weight gain (in kg).
