D)Cannot be determined from the information given

Question

Quizplus · Accepted Answer

The proportion of the variance in Y explained by X is given by the coefficient of determination, which is the square of the correlation coefficient. Therefore, if r = 0.72, then r^2 = 0.52, which means that 52% of the variance in Y is accounted for by its relationship with X. Therefore, the answer is C.
