Provide an appropriate response.

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.
TIME60:  y = Elapsed time (in seconds) from 0 mph to 60 mph
MAX: x1 = Maximum speed attained (miles per hour)
Initially, the simple linear model E(y) = β0 + β1x1 was fit to the data. Computer printouts for the analysis are given below:

UNWEIGHTED LEAST SQUARES LINEAR REGRESSION OF TIME60







CASES INCLUDED 129   MISSING CASES 0

Approximately what percentage, rounded to the nearest whole percent, of the sample variation in acceleration time can be explained by the simple linear model?

▸ 70%

▸ -17%

▸ 8%

▸ 0%
