7. [-72.77 Points] DETAILS ASWSBE14 15.E.011. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The following estimated regression equation based on 10 observations was presented. $ = 29.1290 + 0.5906x + 0,4980x2 The values of SST and SSR are 6,713.125 and 6,219.375, respectively. (a) Find SSE SSE = (b) Compute R2. (Round your answer to three decimal places.) RP = (c) Compute R? (Round your answer to three decimal places.) R2 = (d) Comment on the goodness of fit. (For purposes of this exercise, consider a proportion large if it is at least 0.55.) The estimated regression equation provided good fit as a large proportion of the variability in y has been explained by the estimated regression equation. The estimated regression equation provided a good fit as a small proportion of the variability in y has been explained by the estimated regression equation. The estimated regression equation did not provide a good fit as a small proportion of the variability in y has been explained by the estimated regression equation. The estimated regression equation did not provide good fit as a large proportion of the variability in y has been explained by the estimated regression equation. Need Help? Read It 8.
