The dean of the Business School at a small Florida college wishes to determine whether the​ grade-point average​ (GPA) of a graduate student can be used to predict the graduates starting salary. Records for 23 of last​ year’s Business School graduates were selected and the following​ least-squares regression line was calculated to predict starting salary​ (y) from GPA​ (x) and​ R2=.78. A) Circle the correct interpretation of R2.\ B) Suppose that you were one of the graduates in the study and the residual was negative. This means that
