Ten observations were provided for a dependent variable y and two independent variables $x_1$ and $x_2$; for these data,
SST = 15,172.8 and SSR = 14,061.4.
(a) Compute $R^2$. (Round your answer to three decimal places.)
$R^2 = $
(b) Compute $R^2_a$. (Round your answer to three decimal places.)
$R^2_a = $
(c) Does the estimated regression equation explain a large amount of the variability in the data? Explain. (For purposes of this exercise, consider an amount large if it is at least 55%. Round your
answer to one decimal place.)
_____%, after adjusting for the number of independent variables in the model, we see that ____% of the variability in y has been accounted for.
