You're a researcher and you study narcolepsy. Narcolepsy is a
condition characterized by bouts of uncontrollable sleepiness
throughout the day at unpredictable times. A person may lose
consciousness during one of these "sleep attacks". You believe that if
patients listened to a certain type of music throughout the day in the
