Researchers in obesity wanted to compare the effectiveness of dieting with exercise against dieting without exercise. Seventy-three patients were randomly divided into two groups. Group 1, composed of patients, was put on a program of dieting with exercise. Group 2, composed of patients, dieted only. The results for the weight loss, in pounds, after months are summarized in the following boxplots. The top boxplot is for Group 1 and the bottom boxplot is for Group 2.

Use the boxplots to compare the weight losses for the two groups, paying special attention to center and variation.
