Question

(g) Consider the sample regression equation:. When increases 1 unit and increases 2 units, while and remain unchanged, what change would you expect in the predicted y? A. Decrease by 2 B. Decrease by 4 C. Decrease by 7 D. No change in predicted y (h) Theof a multiple regression of on and measures the: A. Percent variability of y that is explained by the variability of. B. Percent variability of y that is explained by the variability of. C. Statistical significance of the coefficients in the regression equation. D. Percent variability of y that is explained by the variability of and. (i) When two regression models applied on the same data set have the same response variable but a different number of explanatory variables, the model that would evidently provide the better fit is the one with a : A. Lower standard error of the estimate and a higher coefficient of determination. B. Higher standard error of the estimate and a higher coefficient of determination. C. Higher coefficient of determination and a lower adjusted coefficient of determination. D. Lower standard error of the estimate and a higher adjusted coefficient of determination.
