A study of the effect of caffeine on muscle metabolism used 22 male volunteers who each underwent
arm exercise tests. Eleven of the men were randomly selected to take a capsule containing pure caffeine one
hour before the test. The other men received a placebo capsule. During each exercise the subject's respiratory
exchange ratio (RER) was measured. (RER is the ratio of CO2 produced to O2 consumed and is an indicator of
whether energy is being obtained from carbohydrates or fats)
The question of interest to the experimenter was whether, on average, caffeine changes RER. The two
populations being compared are "men who have not taken caffeine" and "men who have taken caffeine".
