Transcribed Image Text:* Instead of slope, intercept, and standard error, show the final fitted equation and coefficient of determination (R²) ** DO repeat the problem with x and y reversed and interpret the results.
**17.3 Use Least-Squares Regression to Fit a Straight Line**

**Table of Data:**

| x | 0 | 2 | 4 | 6 | 9 | 11 | 12 | 15 | 17 | 19 |
|---|---|---|---|---|---|----|----|----|----|----|
| y | 5 | 6 | 7 | 6 | 9 | 8  | 7  | 10 | 12 | 12 |

**Instructions:**

- Compute the slope and intercept of the regression line using least-squares regression.
- Determine the standard error of the estimate and the correlation coefficient.
- Plot the data points and the regression line on a graph.
- Repeat the analysis by regressing x versus y (switch the roles of the variables).
- Interpret the results of both regressions.
