Exercise 15.19 Algo (Testing for Significance) The following estimated regression equation is based on 10 observations was presented. $\hat{y} = 29.1270 + 0.5906x_1 + 0.4980x_2$ Here SST = 6,839.500, SSR = 6,191.375, $s_{b_1} = 0.0824$, and $s_{b_2} = 0.0512$. a. Compute MSR and MSE (to 3 decimals). MSR = MSE = b. Compute $F$ and perform the appropriate $F$ test (to 2 decimals). Use $\alpha = 0.05$. Use the $F$ table. $F$= The p-value is - Select your answer - At $\alpha = 0.05$, the overall model is - Select your answer - c. Perform a t test for the significance of $\beta_1$ (to 2 decimals). Use $\alpha = 0.05$. Use the t table. $t_1$= The p-value is - Select your answer - At $\alpha = 0.05$, there is - Select your answer - relationship between y and $x_1$. d. Perform a t test for the significance of $\beta_2$ (to 2 decimals). Use $\alpha = 0.05$. Use the t table. $t_2$= The p-value is - Select your answer - At $\alpha = 0.05$, there is - Select your answer - relationship between y and $x_2$.
