The estimated regression equation for a model involving two independent variables and 10 observations follows. Here SST = 6,724.125, SSE = 507.75, Sb = 0.0813, and Sb2 = 0.0567. = 29.1270+0.5906x1 + 0.4980x2 h. Use the Ftest to determine the overall significance of the relationship among the variables. Use a = 0.05. F = 41.35; p-value is less than 0.01; The overall model is significant. F = 42.85; p-value is less than 0.01; The overall model is significant. OF = 42.85; critical value is 5.59; The overall model is significant. O F= 42.85; p-value is less than 0.01; The overall model is not significant. i. Perform at test for the significance of X1. Use a 0.05 level of significance. t = 8.78; p-value is less than 0.01; x1 is significant. t = 7.26; critical value is 2.365; x1 is significant. O t = 7.26; p-value is less than 0.01; x1 is significant. O t = 7.26; critical value is 1.895; x1 is significant. j. Perform at test for the significance of x2. Use a 0.05 level of significance. O t = 7.26; p-value is less than 0.01; x2 is significant. t = 8.78; critical value is 2.365; X2 is significant. t = 8.78; critical values are -2.365 and 2.365; X2 is significant. O t = 8.78; critical value is 1.895; X2 is significant. k. Construct a 95% confidence interval for the coefficient of X2. 0.3698 to 0.6387 0.3711 to 0.6403 0.3579 to 0.6215 0.3639 to 0.6321
