Does the estimated regression equation explain a large amount of the variability in the data? - Select your answer - + Explain. Hint: If Ra 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
