Which of the following statements is incorrect? Select one: a. The coefficient of determination is defined as r². b. If r²=0.70, it implies that 70% of the variation in Y is explained by the regression line. c. If r=0.64 then r²=0,4096. O d. r indicates the strength and the direction of the relationship between X and Y variables. O e. The coefficient of correlation r can never be negative.

10.4.9 Question Help 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? E Click the icon to view the table of regression equations. The best variable is V because it has the best combination of V P-value, , and adjusted R2, (Type integers or decimals. Do not round.)
