Consider the following data for a dependent variable y and two independent variables, *1 and 22; for these data SST = 15,151.6, and SSR = 14,231.5. T2 y 30 12 95 47 10 109 25 18 113 51 17 178 41 5 95 52 19 176 74 7 171 37 12 117 59 13 142 76 17 212 Round your answers to three decimal places. a. Compute R2. 0.061 b. Compute Ra . -0.207 c. Does the estimated regression equation explain a large amount of the variability in the data? Yes Explain. Hint: If Ro is greater than 70%, the model explains a large amount of variability. Since the adjusted coefficient of determination is |greater than 70%, the model does v explain a large amount of variability
