The following estimated regression equation based on 30 observations was presented. $\hat{y} = 17.6 + 3.8x_1 - 2.3x_2 + 7.6x_3 + 2.7x_4$ The values of SST and SSR are 1,801 and 1,752, respectively. (a) Compute $R^2$. (Round your answer to three decimal places.) $R^2 = \boxed{\phantom{12345}}$ (b) Compute $R_a^2$. (Round your answer to three decimal places.) $R_a^2 = \boxed{\phantom{12345}}$ (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 y has been explained by the estimated regression equation. O 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. O 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. O 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.
