In a regression analysis involving 29 observations, the following estimated regression equation was developed. y = 20.1 +5.65 For this estimated regression equation SST = 1390 and SSE = 470. Do not round Intermediate calculations. a. At a = 0.05, test whether 1 is significant. (to whole number) MSR 920 DF 27 MSE 18 F (to whole number) 51.11 (to 2 decimals) p-value is - Select your answer ®, so So Is not statistically significant Suppose that variables 22 and are added to the model and the following regression equation is obtained. y = 17+2.5x) +10.873 – 6.603 For this estimated regression equation SST = 1390 and SSE - 170. b. Use an F test and a 0.05 level of significance to determine whether #2 and 13 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 Ig and - Select your answer! statistically significant
