Question

Quizplus · Accepted Answer

The coefficient of determination, R^2, represents the proportion of the total variation in the dependent variable that is accounted for by the regression equation. In this case, R^2 = 0.64, which means that 64% of the variation in y is explained by the regression equation. Therefore, the correct answer is D.
