The coefficient of determination (r-squared) is the percentage of variance in the criterion variable that can be explained by the predictor variable. It is calculated by squaring the correlation coefficient (r). So, r-squared = .84^2 = .7056, which is approximately 71%. Therefore, the answer is C) 71%.
