Consider the data. 1 2 4 5 y; 5 11 13 The estimated regression equation for these data is y = 1.90 + 2.10x. (a) Compute SSE, SST, and SSR using equations SSE = Z(y, - > ) , SST = >(y; - y)2, and SSR = >(9, - >)2. SSE = SST = SSR = (b) Compute the coefficient of determination /2. 12 = Comment on the goodness of fit. (For purposes of this exercise, consider a proportion large if it is at least 0.55.) O The least squares line provided a good fit as a small proportion of the variability in y has been explained by the least squares line. The least squares line provided a good fit as a large proportion of the variability in y has been explained by the least squares line. The least squares line did not provide a good fit as a small proportion of the variability in y has been explained by the least squares line. O The least squares line did not provide a good fit as a large proportion of the variability in y has been explained by the least squares line. (c) Compute the sample correlation coefficient. (Round your answer to three decimal places.)
