Transcribed Image Text:### Instructions
Use a graphing calculator to create a scatter plot and find the line of best fit and the correlation coefficient for the following data. Round to the nearest hundredth.
### Data Table
| x | y |
|----|----|
| 2 | 2 |
| 4 | 3 |
| 6 | 6 |
| 8 | 7 |
| 10 | 10 |
| 12 | 15 |
| 14 | 19 |
### Steps to Follow
1. **Create a Scatter Plot:**
- Input the x-values and y-values into the graphing calculator.
- Plot each (x, y) point on a coordinate grid.
2. **Find the Line of Best Fit:**
- Use the calculator's linear regression function to determine the equation of the line of best fit.
3. **Calculate the Correlation Coefficient:**
- The calculator will also provide the correlation coefficient (denoted as 'r'), which indicates how well the line fits the data.
4. **Round Results:**
- Ensure that all numerical results, including the slope, intercept, and correlation coefficient, are rounded to the nearest hundredth.
