en observations were provided for a dependent variable y and two independent variables x, and x,; for these data, SST = 15,173.3 and SSR = 14,064.1. (a) Compute R . (Round your answer to three decimal places.) R2 = (b) Compute R . (Round your answer to three decimal places.) R. (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-v, after adjusting for the number of independent variables in the model, we see that % of the variability in y has been accounted for
