In a Multiple Regression Problem, the Regression Sum of Squares $\sum(\hat{y}-\bar{y})^{2}=12,000$

Short Answer

In a multiple regression problem, the regression sum of squares is $\sum(\hat{y}-\bar{y})^{2}=12,000$ and the total sum of squares is $\sum(y-\bar{y})^{2}=20,000$ . Find the value of the multiple correlation coefficient.
