Timber yield is approximately equal to the volume of a tree, however, this value is difficult to measure without first cutting the tree down. Instead, other variables, such as height and diameter, may be used to predict a tree's volume and yield. Researchers wanting to understand the relationship between these variables for black cherry trees collected data from 31 such trees in the Allegheny National Forest, Pennsylvania. Height is measured in feet, diameter in inches (at 54 inches above ground), and volume in cubic feet.

$$\begin{array}{rrrrr} \hline & \text { Estimate } & \text { Std. Error } & \mathrm{t} \text { value } & \operatorname{Pr}(>|\mathrm{t}|) \\ \hline \text { (Intercept) } & -57.99 & 8.64 & -6.71 & 0.00 \\ \text { height } & 0.34 & 0.13 & 2.61 & 0.01 \\ \text { diameter } & 4.71 & 0.26 & 17.82 & 0.00 \\ \hline \end{array}$$

(a) Calculate a $95 \%$ confidence interval for the coefficient of height, and interpret it in the context of the data.

(b) One tree in this sample is 79 feet tall, has a diameter of $11.3$ inches, and is $24.2$ cubic feet in volume. Determine if the model overestimates or underestimates the volume of this tree, and by how much.
