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: = Maximum speed attained (miles per hour)
Initially, the simple linear model E(y) = + was fit to the data. Computer printouts for the analysis are given below: Find and interpret the estimate in the printout above.
