In a comprehensive road test on all new car models, one variable measured is the time it takes a car to accelerate from 0 to 60 miles per hour. To model acceleration time, a regression analysis is conducted on a random sample of 129 new cars. Initially, the simple linear model E(y) Bo + B1x, was fit to the data. Computer printouts for the analysis are provided below. Approximately what percentage, rounded to the nearest whole percent, of the sample variation in acceleration time can be explained by the simple linear model? Click the icon to view the analysis. O A. 70% O B. 0% O C. 8% O D. - 17%
