Use the regression equation below for predicting graduate GP

Use the regression equation below for predicting graduate GPA for the three presented cases.

            Y? = -1.636 + 0.793(undergrad GPA) + 0.004(GREverbal)

Solution

Y? = -1.636 + 0.793(undergrad GPA) + 0.004(GREverbal) - 0.0009(GREquant)?

+ 0.009(Motivation)

(1) Y\' = -1.636 + 0.793(2.9) + 0.004(560) - 0.0009(540)? + 0.009(55) = 2.91

(2) Y\' = -1.636 + 0.793(3.2) + 0.004(550) - 0.0009(590)? + 0.009(65) = 3.16

(3) Y\' = -1.636 + 0.793(3.4) + 0.004(600) - 0.0009(550)? + 0.009(70) = 3.60
