The results of the study are presented below:
$\begin{array} { l c l } \text { Predictor } & \text { Coef } & \text { SE Coef } \\ \text { Constant } & 35.178 & 7.595 \\ \text { Degree } & 0.22073 & 0.07131 \\ \text { Age } & 0.3353 & 0.1901 \\ \text { Salary } & 0.0930 & 0.1675 \end{array}$
$s = 7.62090$
Analysis of Variance
$\begin{array} { l c c } \text { Source } & \text { DF } & \text { SS } \\ \text { Regression } & 3 & 1053.09 \\ \text { Residual Error } & 32 & 1858.50\\\\ \text { Source } & \text { DF } & \text { Seq SS } \\ \text { Degree } & 1 & 672.10 \\ \text { Age } & 1 & 363.09 \\ \text { Salary } & 1 & 17.90 \end{array}$
