ŷ 29.1290 + 0.5806x1 +0.4380x2
The values of SST and SSR are 6,716.125 and 6,228.375, respectively.
(a) Find SSE.
SSE =
(b) Compute R². (Round your answer to three decimal places.)
R²
2.
(c) Compute R₂². (Round your answer to three decimal places.)
Ra
(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 did not provide a good fit as a large 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 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 provided a good fit as a large proportion of the variability in y has been explained by the estimated regression equation.
