Jorge would like to examine the effects of fatigue on mental alertness. He prepares an attention test that requires subjects to sit in front of a blank TV screen and press a response button each time a dot appears on the screen. A total of 110 dots is presented during a 90-minute period, and Jorge records the number of errors for each subject. Two groups of subjects are selected. The first group of subjects is tested after they have been kept awake for 24 hours. The second group is tested in the morning after a full night’s sleep.
