Chapter 7, Problem 3(choose chapter or problem)
A least-squares line is fit to a set of points. If the total sum of squares is \(\sum\left(y_{i}-\bar{y}\right)^{2}=9615\), and the error sum of squares is \(\sum\left(y_{i}-\widehat{y}_{i}\right)^{2}=1450\), compute the coefficient of determination \(r^2\).
