The following estimated regression equation based on 10 observations was presented. ŷ = 29.1210 + 0.5806x₁ + 0.4280x₂ The values of SST and SSR are 6,723.125 and 6,224.375, respectively. (a) Find SSE. SSE = (b) Compute R². (Round your answer to three decimal places.) R² = (c) Compute Rₐ². (Round your answer to three decimal places.) Rₐ² = (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 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. 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 a good fit as a large proportion of the variability in y has been explained by the estimated regression equation.

Transcript

00:01 In this problem, we are given that in a linear regression equation, it is observed that the value of ssr, which is the sum of the squared residuals, this is equal to 325.

00:18 And the value of sst representing the total sum of squares, this is 550.

00:25 And we have to determine the value of sse, which is the sum of the squared, errors.

00:32 So to find this, we simply use this formula and put the values...
