To estimate the average change in mood rating associated with a 1 hour increase in hours online, we need to examine the scatter plot shown in the image. However, since the scatter plot is not visible directly, I'll explain the general approach to solving this type of problem:

1. **Identify the trend in the scatter plot:** Look at how the points are distributed. If the points show a downward trend as the number of hours online increases, this indicates a negative correlation.

2. **Calculate the slope of the trend line:** The slope of the best fit line (trend line) through the scatter plot points represents the average change in mood rating per hour of internet use. If the slope is steep and downward, the change in mood rating is more negative. If the slope is shallow, the change is less negative.

3. **Select the closest value to the slope:** Choose the option that best matches the estimated slope.

### Analyzing the Given Options:
- **Option A: -4 points** suggests a steep negative slope.
- **Option B: -2 points** suggests a moderately steep negative slope.
- **Option C: -1 point** suggests a mild negative slope.
- **Option D: -1/2 point** suggests a very mild negative slope.

Without the visual information, based on typical survey results where excessive internet use often correlates with a slight decrease in mood, the most reasonable answer is likely a mild negative change.

### Answer:
The best estimate of the average change in mood rating associated with a 1 hour increase in hours online is:

**C. -1 point**

This choice indicates that for every additional hour spent online, the mood rating decreases by approximately 1 point on average.
