Dr. Paul discovers a new chemical that he predicts will increase energy levels in hamsters. He designs an experiment to test his
prediction
Dr. Paul separates 12 hamsters into two equal groups. He gives one group of hamsters the chemical but does not give the
chemical to the other group. He keeps everything else about the hamsters' living environment the same.
Over the next month, Dr. Paul measures the time that the hamsters spend running on their exercise wheels each day. He then
calculates averages for these measurements, which are shown in the table below.
