Exercise 15.12 Algo (Multiple Coefficient of Determination) Consider the following data for a dependent variable y and two independent variables, @1 and @:2; for these data SST = 15,250.4, and SSR = 14,320.7. y 30 13 94 46 10 109 25 17 112 51 17 178 41 6 94 52 20 176 74 8 171 37 13 117 59 14 142 77 16 211 Round your answers to three decimal places. a. Compute R b. Compute Ra c. Does the estimated regression equation explain a large amount of the variability in the data? - Select your answer - v 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 - v| explain a large amount of variability
