Coach Damien notices that some of his football players drink more water than others before Friday night games. He is interested if the amount of water the students drink affects their endurance. One week before practice he has each student drink a bottle of water throughout the day. That afternoon, they run the bleachers and he records how many times each player can go up and back before stopping to catch their breath. The next week they do the same thing but drink 2 bottles of water beforehand. The third week they run the bleachers but drink a gallon of water beforehand.
