Use the data in the table below to complete parts (a) through (c):
| x | y |
|----|----|
| 5 | 32 |
| 7 | 35 |
| 8 | 27 |
| 9 | 22 |
| 15 | 25 |

Click the icon to view the steps for finding influential points.
**(a) Construct a scatterplot of the data. Choose the correct graph below:**
- O A.
- This scatterplot has axes marked from 0 to 50 on both x and y. Several data points are plotted.
- O B.
- This plot shows axes ranging from -12 to 40 on the x-axis and the y-axis, featuring plotted points.
- O C.
- Depicts axes from 0 to 40 on the x-axis and y-axis, with plotted points.
- O D.
- A plot with x and y ranging from -12 to 40, shows scattered points.
**(b) Identify any possible outliers.**
- O A. The point (7, 35) may be an outlier.
- O B. The point (48, 4) may be an outlier.

This exercise involves analyzing a set of data points to identify the correct graphical representation and potential outliers.
![## Data and Outliers Analysis
### Data Table
The table below lists pairs of values for \( x \) and \( y \):
| \( x \) | \( y \) |
|---------|---------|
| 5 | 32 |
| 7 | 35 |
| 8 | 27 |
| 9 | 22 |
| 15 | 25 |
| 16 | 24 |
| 18 | 23 |
| 48 | 4 |
### Steps for Identifying Influential Points
There is an interactive section (clickable icon not shown) where steps to find influential points can be accessed.
### Graphs
- A number line graph showing range from 0 to 50.
- A number line graph showing range from -12 to 42.
- Additional interactive graphs not fully visible.
### (b) Identify Any Possible Outliers
Choose the point that may be an outlier:
- \( \text{A. The point } (7,35) \text{ may be an outlier.} \)
- \( \text{B. The point } (48,4) \text{ may be an outlier.} \)
- \( \text{C. The point } (18,23) \text{ may be an outlier.} \)
- \( \text{D. The point } (5,32) \text{ may be an outlier.} \)
- \( \text{E. There are no outliers.} \) *(Currently selected option)*
### (c) Determine if the Point is Influential
Determine if a point is influential based on change in slope or intercept — significant if change is larger than 10%.
- The point [dropdown selection] is [dropdown selection: significant] significantly different, and the intercept is [dropdown selection: significant] significantly different.
