A multiple regression equation with two predictor variables

A multiple regression equation with two predictor variables produces R2 = 0.10. What portion of the variability for the Y scores is predicted by the equation

1%

10%

90%

99%

Solution

the portin of the variabiliy for the T scores is predicted by the equation is 10%

because R^2 means the percentage of variation of Y that is predicted by the model ( equation

answer 10%
