Questions Exercise 15.12 (Multiple Coefficient of Determination) 1, 2. Consider the following data for a dependent variable y and two independent variables, @1 and @2; for these data SST = 15,182.9, and SSR = 14,052.2. C2 y 30 12 94 47 10 108 25 17 112 51 16 178 40 5 94 51 19 175 74 7 170 36 12 117 59 13 142 76 16 211 Round your answers to three decimal places. a. Compute R2 . b. Compute Ra . c. Does the estimated regression equation explain a large amount of the variability in the data? - Select your answer - 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 - V than 70%, the model - Select your answer - V explain a large amount of variability.Questions Exercise 15.12 Algo (Multiple Coefficient of Determination) 1. 2.
