Question 3 (6marks) Fifty subjects who completed a weight-reduction program at a fitness center were divided into two equal groups. Subjects in group 1 were immediately assigned to a support group that met weekly. Subjects in group 2 did not participate in support group activities. All subjects were followed for a period of 60 weeks. They reported weekly to the fitness center, where they were weighed and a determination was made as to whether they were within goal. Subjects were considered to be within goal if their weekly weight was within 5 pounds of their weight at time of completion of the weight reduction program. Survival was measured from the date of completion of the weight-reduction program to the termination of follow-up or the point at which the subject exceeded goal. The following results were observed: subj 1 weeks status group subj weeks status group 60 G 1 1 20 G+ 2 2 32 L 1 2 26 G+ 2 3 60 G 1 3 10 G+ 2 4 22 L 1 4 2 G+ 2 5 6 G+ 1 5 36 G+ 2 6 60 G 1 6 10 G+ 2 7 60 G 1 7 20 G+ 2 8 20 G+ 1 8 18 L 2 9 32 G+ 1 9 15 G+ 2 10 60 G 1 10 22 G+ 2 11 60 G 1 11 4 G+ 2 12 8 G+ 1 12 12 G+ 2 13 60 G 1 13 24 G+ 2 14 60 G 1 14 6 G+ 2 15 60 G 1 15 18 G+ 2 16 14 L 1 16 3 G+ 2
