Half of them are randomly assigned to take a caffeine supplement before working out, and the other half are assigned to take a placebo before completing the same workout. During the workout, heart rate monitors will be used to measure each participant’s heart rate. The study found that those who took a caffeine supplement had significantly higher average pulse rates during the workout. What conclusion can be drawn from the study? (A) Two experimental groups of 20 each is too small to conclude that the results are significant. (B) Those that took the caffeine supplement had a higher average heart rate during the workout, but it would not be correct to conclude that caffeine caused this to occur. (C) The caffeine supplements caused the heart rates to increase due to the placebo effect.
