C)0.36
D)0.77

Question

Quizplus · Accepted Answer

The coefficient of correlation (r) and the coefficient of determination (r^2) are related as follows: r^2 = (r)^2. So, in this case, r^2 = (-0.60)^2 = 0.36. Since the coefficient of determination represents the proportion of variance in one variable that can be explained by the other variable, it must be a positive value between 0 and 1. Therefore, option C is the only possible choice.
