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?

+1 C

If we demonstrate that there are people who lose weight and gain strenght with only excercises, and not using Dietol, we could not conclude that Dietol is helping people who buy it.

Correct in 1:10

A) What was the daily dose of Dietol that the subjects were required to take? Has no bearing on the conclusion that, "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.
b) What was the maximum weight lost by any participant during the 9-week program? We are consistently covering averages through entire argument, no need to change to extremes
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? Correct, restates conclusion and takes into account a different alternative that would not weaken or strengthen the conclusion
d) What was the average age among the subjects participating in the experiment? No bearing on conclusion stated
e) Did the majority of subjects experience a significant improvement in physical strength? off topic at hand

There is one massive confounding variable in the study: the 2-hours of physical training with a professional trainer (that's quite a nice perk for taking part in the study ). For the researchers to claim that the improved benefits were from the use of Dietol is highly suspect. Imagine your friend tells you that he/she has been working out 2-hours a day with a professional trainer. And every morning they say a magic chant. If you congratulate him/her on her new svelte form and ask what the trick was, you would definitely be skeptical if he/she answered: my magic chant.

This study, however, is no different. Therefore, we would need a study that either eliminate the 2-hour training sessions, or tests 2-hour training sessions without Dietol to see the effects. The latter will help us evaluate the conclusion because now we can clearly determine the effects of 2-hour daily training. Therefore the answer is (C).

Hope that helps .

Here the correct answer is C as it is only one which makes some sense and it stands out.
