Compute SST, SSR, and SSE (to 3 decimals). SST = SSR = SSE = b. Compute the coefficient of determination r (to 3 decimals). 72 = Comment on the goodness of fit. Hint: If r is greater than 0.70, the estimated regression equation provides a good fit. The least squares line - Select your answer - a good fit as proportion of the variability in y has Select your answer -
