Jimmy wanted to create a study to test the effects of jazz on people's sleep patterns. He thought that if people listened to jaz
z music as they fall asleep, they will sleep for longer periods of time. For the experiment, 2 groups of 10 people were created. The test was conducted in a sleep lab facility with each room being exactly identical. One group was placed in a quiet room where they went to sleep and they were timed on how long they slept. The other group was placed in a room where jazz music played
softly as they began to sleep and played throughout the night. As each group awoke, their sleep times were monitored.
