In a regression analysis involving 30 observations, the following estimated regression equation was obtained. y = 17.6 +3.821 -2.322 + 7.633 +2.714 For this estimated regression equation SST = 1805 and SSR = 1768. a. At a = 0.05, test the significance of the relashionship among the variables. SSE 37 (to 1 decimal, if necessary) (to 1 decimal, if necessary) MSR MSE (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 p value? Select your answer Using a 0.05, what is your conclusion? Select your answer Suppose vanables 11 and 24 are dropped from the model and the following estimated regression equation is obtained. 11.1- 3,63 +8.133 For this model SST1805 and SSR - 1,705 b. Compute SSE(L1, 12, 13, 14). (to 1 decimal, if necessary) C. Compute SSE(#2, #3) (to 1 decimal, if necessary) d. Use an F test and a = 0.05 to determine whether 21 and 4 contribute significantly to the model What is the value of the F test statistic (to 2 decimals)? Use Table 4 in Appendix B. d. Use an F test and a = 0.05 to determine whether 21 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 21 and 24? - Select your
