Question 74, 10.4.9 HW Score: 53.71%, 67.13 of 125 points X Points: 0 of 2 Save The accompanying table shows results from regressions performed on data from a random sample of 21 cars. The response (y) variable is CITY (fuel consumption in mi/gal). The predictor (x) variables are WT (weight in pounds), DISP (engine displacement in liters), and HWY (highway fuel consumption in mi/gal). If only one predictor (x) variable is used to predict the city fuel consumption, which single variable is best? Why? Click the icon to view the table of regression equations. The best variable is because it has the best combination of P-value, and adjusted R. (Type integers or decimals. Do not round.) - X Regression table Predictor (x) Variables P-Value R2 Adjusted R Regression Equation WT/DISP/HWY 0.000 0.942 0.932 CITY =6.86 -0.00128WT - 0.257DISP + 0 656HWY WT/DISP 0.000 0.747 0.719 CITY =38.1 - 0.00159WT - 1.28DISP WT/HWY 0.000 0.943 0.937 CITY = 6.69 - 0.00159WT + 0.668HWY DISP/HWY 0.000 0.934 0 927 CITY = 1.87 - 0.621DISP + 0.709HWY WT 0.000 0.712 0.697 CITY = 41.6 - 0.00606WT DISP 0.000 0.658 0.640 CITY = 29.3 -2.98DISP HWY 0.000 0.923 0.919 CITY = -3.11 +0.824HWY Textbook Print Done er
