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 background it might minimize these sleep attacks. You had participants count the number of sleep attacks they had one week before and one week after instituting a constant stream of barely audible, soothing music into their home environment. The data are shown below. Subject Before After music music Difference 11 6. 13 10 3 9. 8 10 7. 5. 12 13 8. 8 00 1. 2. 4. 6

Question
Can you conclude that listening to music will decease the frequency of sleep attacks in narcoleptics at p=0.05?
--- ### Exploring the Impact of Music on 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 background, it might minimize these sleep attacks. To test this hypothesis, you had participants count the number of sleep attacks they had one week before and one week after instituting a constant stream of barely audible, soothing music into their home environment. The data are shown below. | Subject | Before music | After music | Difference | |---------|--------------|-------------|------------| | 1 | 11 | 9 | -2 | | 2 | 13 | 10 | -3 | | 3 | 9 | 6 | -3 | | 4 | 10 | 7 | -3 | | 5 | 12 | 13 | +1 | | 6 | 8 | 8 | 0 | **Explanation of the Data**: - **Subject**: Identifies each participant. - **Before music**: Number of sleep attacks experienced by the participant one week before the introduction of music. - **After music**: Number of sleep attacks experienced by the participant one week after the introduction of music. - **Difference**: The change in the number of sleep attacks before and after the introduction of music. Negative values indicate a reduction in sleep attacks, while positive values indicate an increase. **Note**: The table suggests a general trend towards fewer sleep attacks for most subjects after listening to soothing music, although there are exceptions. Further studies with larger sample sizes and varied conditions could provide more definitive results. ---
