and y= overall soore. S5T = 55R= S5L = (b) Compute the coefficicnt of determination r2 (Round your answer to three decimal places.) x2= Comment on the goodness of fit. (For purposes of this exercise, consider a proportion large if it is at leapt 0.55 .) The least squares line did not provide goed fit as a large proportion of the variability in y has been explained by the least squares line. The least squares line provided a gond fit as a small propertion of the vartabiliy in y has been explained by the least squares line. The. least squares line did not provide a geod fit as a amall propornon of the yailabiliy in y has been explaihed ty the least squares Nhe. The least squares ine provided a goed fit as a targe proportboe of the variability in y has been explained by the lesst sgiares line
