**Understanding Narcolepsy and the Effects of Music Therapy**

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". 

**Research Hypothesis**:

As a researcher, you hypothesize that listening to a certain type of music throughout the day might minimize these sleep attacks. To test this, participants were asked to count the number of sleep attacks they had one week before and one week after introducing a constant stream of barely audible, soothing music into their home environment. 

**Data Collection**:

The data collected from this experiment is shown below:

| Subject | Before Music | After Music | Difference |
|--------|--------------|-------------|------------|
| 1      | 11           | 9           | 2          |
| 2      | 13           | 10          | 3          |
| 3      | 9            | 9           | 0          |
| 4      | 10           | 7           | 3          |
| 5      | 12           | 13          | -1         |
| 6      | 8            | 8           | 0          |

This table provides insights into the effectiveness of music therapy in reducing sleep attacks among narcolepsy patients. Each participant's data before and after the music therapy is displayed, along with the calculated difference in the number of sleep attacks.

**Analysis and Interpretation**:

The data can be analyzed to determine if the music had a significant effect on reducing the number of sleep attacks. Positive differences indicate a reduction in sleep attacks, while negative differences suggest an increase. 

This type of research can pave the way for non-pharmaceutical interventions to manage symptoms of narcolepsy and improve the quality of life for those affected.
