QUESTION 6 Given the model y = Bo + B1X1 + B2X2 + B3X12+ B4X22+ and with n = 20; Which test do we use to test if the squared terms are significant to the model, when taken together? OA. Partial F-test B. T-test C. F-test D. Durbin Watson QUESTION 7 Given the model y = Bo + B1X1 + B2X2 +33X12+ B4X22+ and with n= 20; Which test do we use to test if the model is useful? A. T-test B. F-test C. Partial F-test D. Durbin Watson
QUESTION 8 Given the model y = Bo + B1X1 + B2X2 + B3X12+ B4X2²- +E and with n=20 What is the null hypothesis for testing the squared terms as significant to the model when taken together? A. Ho: B3 B40 = B. Ha: at least one beta not equal to zero OC. Ho: B3 = 0 O D. Ho: B1 B2 B3 =B4 = 0 = QUESTION 9 Refer to question 8. We can reject Ho if the partial F test statistic is (with n= 20) A. >3.06 B. <3.06 C.>3.68 D.<3.68
