Question
A study was done to compare tree height with trunk thickness. The following output was generated from the regression model.
Simple linear regression results:
Dependent Variable: Tree Height
Independent Variable: Trunk Size
Height = 39.041668 + 8.668677 Trunk
R (
R-sq = 0.1952
Estimate of error standard deviation: 10.09977
Parameter estimates:
| Parameter | Estimate | Std. Err. |
| Intercept | 39.041668 | 15.1736 |
| Trunk | 8.668677 | 3.670058 |
Assuming the conditions are met test if trunk size is a good predictor of tree height
