4. [-l1 Points] DETAILS ASWSBE1415.E.013.MI. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The following estimated regression equation based on 30 observations was presented. 3? = 17.6 + 3.8;(1 2.3x2 + 7.6)(3 + 2.7x4 The values of SST and SSR are 1,801 and 1,759, respectively. (a) Compute R2. {Round your answer to three decimal places.) R2 [:l (b) Compute Raz. (Round your answer to three decimal places.) (c) Comment on the goodness of fit. (For purposes of this exercise, consider a proportion large if it is at least 0.55.) O The estimated regression equation provided a good fit as a small proportion of the variability in 1/ has been explained by the estimated regression equation. 0 The estimated regression equation did not provide a good t as a small proportion of the variability in y has been explained by the estimated regression equation. 0 The estimated regression equation provided a good fit as a large proportion of the variability in y has been explained by the estimated regression equation. 0 The estimated regression equation did not provide a good fit as a large proportion of the variability in y has been explained by the estimated regression equation
