10.
Ans: c. the goodness of fit of the regression.
Explanation: Change in unit or scaling of dependent variable can never affect R-squared (or correlation) between dependent variables and regressors as R-squared is focused only on how much % variation in dependent variable is explained by regressors.

For two valid regression models which have same dependent variable, if regression model A and regression model B have the followings, Regression A: Residual Standard error = 30.33, Multiple R squared = 0.764, Adjusted R squared = 0.698 Regression B: Residual Standard error = 40.53, Multiple R squared = 0.784, Adjusted R squared = 0.658 Then which one is the correct one? Choose all applied. a. Model A is better than B since Model A has smaller residual standard error...
