In a regression analysis involving 29 observations, the following estimated regression equation was developed. y=20.1 +5.631 For this estimated regression equation SST = 1390 and SSE = 470, Do not round Intermediate calculations. a. At a = 0.05, test whether 21 is significant 920 (to whole number) MSR DF 27 MSE 17 (to whole number) F 59.80 (to 2 decimals) p-value is Select your answer.so 21 Is statistically significant Suppose that variables 12 and us are added to the model and the following regression equation is obtained. y = 17+2.521 +10.873 - 6.623 For this estimated regression equation SST = 1390 and SSE = 170. b. Use an F test and a 0.05 lēvel of significance to determine whether #2 and is contribute significantly to the model. What is the value of the F test statistic? Use Table 4 in Appendix B. (to 2 decimals) p-value is Select your answer. so addition of variables 22 and I Is not statistically significant
