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
Sample size: 25
R (correlation coefficient) = 0.4418
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
