Calculate R-squared,--the coefficient of determination-given that the linear correlation coefficient, r, is 0.817. What does this tell you about the explained variation and the unexplained variation of the data about the regression line? O a. The coefficient of determination (R2) = 0.667. That is, 66.7% of the variation is explained and 33.3% of the variation is unexplained O b. The coefficient of determination (R2) = 0.667. That is, 66.7% of the variation is unexplained and 33.3% of the variation is explained c. Not enough information is given.
