Exercise 15.12 A Multiple Coefficient of Determination Hint(s) Check My Waork Consider the following data for a dependent variable g and two independent variables, @y and @y for these data 88T = 15,050.6, and S8R = 14,073.1. Round your answers to three decimal places. a. Computs B2 . o b. Compute RE i 9 . Does the estimated regression equation explain a large amount of the variability in the data? g0 o 30 46 25 51 a1 51 74 36 60 76 oy 13 10 17 17 5 19 7 12 13 16 95 109 113 178 94 176 171 118 143 211 Explain. Hint: If RE is greater than l%, the model explains a large amount of variability. Since the adjusted coefficient of determination is & than TO%, the model @ explain a large amount of varability
