A certain pharmaceutical firm claims that its dietary supplement, Dietol, is highly effective in helping obese people lose weight and improve physical endurance. The company supports this claim by providing the results of a recent experiment that involved over 800 subjects suffering from obesity. During the 9-week experiment, each of the subjects was required to take a regular dose of Dietol every day immediately after their daily 2-hour workouts supervised by a professional fitness instructor. As a result of the experiment, the subjects lost an average of 12 pounds of weight per person, and over 95% of all participants demonstrated higher physical endurance. The answer to which of the following questions would be most helpful in evaluating the conclusion of the pharmaceutical company?

A. What was the daily dose of Dietol that the subjects were required to take?

B. What was the maximum weight lost by any participant during the 9-week program?

C. What would be the average weight loss and the improvement in endurance in a group of subjects with similar characteristics involved in the same physical fitness program but not taking
Dietol?

D. What was the average age among the subjects participating in the experiment?

E. Did the majority of subjects experience a significant improvement in physical strength?
