A football coach hears that a new exercise program will increase upper-body strength better than lifting weights. He is eager to test this new program in the off-season with the players on his high school team. The coach decides to let his players choose which of the two treatments they will undergo for three weeks - exercise or weight lifting. At the end of three weeks, he will have each player do push-ups to failure (until they can't do any more.) 1)What part of the coach's plan did not follow the rules for a well designed experiment? Explain your answer. 2)Describe a way to correct this flaw so that the experiment is valid and well designed.
