Q2 Thirty observations were employed in a multiple regression model for predicting Y from X1, X2 and Xs. When the full model was fitted, the residual sum of squares was 650 (SSRES, full=650) and type I and type II sum of squares were as shown below: Source X1 X2 X3 Type ISS 100 140 60 Type II SS 20 120 60 2 Test at the 5% level to see if any prediction is possible from the full model. Frable = 2.98 Hint You should obtain an ANOVA table. b. Would prediction be as good if X2 were deleted from the model? Use a = 0.05. Flable = 4.23
