Ten observations were provided for a dependent variable y and two independent variables x1 and x2; for these data, SST = 15,182.4 and SSR = 14,064.2. (a) Compute RZ. (Round your answer to three decimal places.) R2 = (b) Compute Ra. (Round your answer to three decimal places.) Ra (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.) --Select--- , after adjusting for the number of independent variables in the model, we see that % of the variability in y has been accounted for. Need Help?
