1. A scientist wants to test the sleeping effects of a mild animal tranquilizer on two of his pet rats. He decides that he will put them in two cages of the same size and shape and place them in the same area of his lab for 24 hrs. He decides that he is going to turn the lights on at 5am and turn the lights of at 8pm each day. He feeds both rats lunch each day at noon and chops up 5mg of animal tranquilizer into their food. He notes that at about 5pm both rats fall asleep and wake up at about 5am the following day. He continues this procedure for 15 days and notes the same pattern each day. He concludes that his study shows that the animal tranquilizer will cause all animals to fall asleep at 5pm for a total of 12 hrs.
