An experimenter sets out to find out how many hours of sleep a dog needs in order to catch the highest number of balls without a bounce. To test this the experimenter uses 5 dogs in the experiment and allows each dog to sleep a predetermined amount of time: dog 1: 4 hrs, dog 2: 6 hrs, dog 3: 8 hours, dog 4: 12 hours, dog 5: 16 hours. If a dog sleeps of its own free, will it is normal for a dog to sleep for 8 hrs. After having the dogs establish these sleep patterns the experimenter through each dog 20 balls and recorded the number each one caught.
Dog1 5% Caught
Dog 2 15% caught
Dog3 50% caught
Dog 4 97% caught
Dog5 2% caught
