3. A study was created to test the effects of jazz music on people's sleep patterns. The hypothesis of the experiment was that if people listened to jazz music as they fell asleep, they would sleep for longer periods of time. For the experiment, 2 groups of people were created. One group was placed in a quiet room where they went to sleep and they were timed on how long they slept. The second group was placed in a similar room where jazz music played softly as they began to sleep and played throughout the night. As each group awoke, their sleep times were recorded. (4 points)
