Compute R2 . b. Compute R. . c. Does the estimated regression equation explain a large amount of the variability in the data? - Select your answer - v Explain. Hint: If Ru is greater than 70%, the model explains a large amount of variability. Since the adjusted coefficient of determination is |- Select your answer - | than 70%, the model - Select your answer - |explain a large amount of variability. Check My Work
