Question: It has been reported that healthy, athletic adults exercise for an average of 5 hours per week. You are interested in seeing if a medical treatment will allow otherwise-healthy adults to be able to exercise more without suffering injuries. You select a sample of 50 local athletes, and have one group of 25 serve as a control (medication is a placebo), and the other group of 25 receives the actual medication. You are interested in showing that group receiving the medication exercised more hours per week without injury than the group receiving the placebo. You find that the group receiving the placebo reported exercising 4.6 hours per week, with an SD of 1.5, while the treatment group reported exercising 5.7 hours per week, also with an SD of 1.5.
