SSE l 41 l g (to 1 decimal, if necessary) MSR l 352.8 l e (to 1 decimal, if necessary) MSE l l 0 (to 2 decimals, if necessary} What is the value of the F test statistic (to 2 decimals)? Use Table 4 in Appendix B. What is the pevalue? 0 Using a = 0.05, what is your conclusion? I Selectynur answer le Suppose variables 31 and 14 are dropped from the model and the following estimated regression equation is obtained. 3:! = 11.1 3.6572 + 8.12:3 For this model SST : 1305 and SSH = 1,705. b. Compute SSE(1, 2, :13, $4). || 0 (to 1 decimal, if necessary) I:. Compute SSE(22, m3]. ll 0 (to 1 decimal, if necessary) d. Use an F test and a = 0.05 to determine whether @1 and 24 contribute significantly to the model. What is the value of the F test statistic (to 2 decimals)? Use Table 4 in Appendix B. What is the p-value? - Select your answer - What is your conclusion about the two variables @1 and 4? - Select your answer - X
