Suppose that the mean time for a certain car to go from 0 to 60 miles...

Suppose that the mean time for a certain car to go from 0 to 60 miles per hour was 7.5 seconds. Suppose that you want to test the claim that the average time to accelerate from 0 to 60 miles per hours is longer than 7.5 seconds. Set up the hypothesis test for this claim. Use a 1% level of significance.

In a comprehensive road test on new car models, one variable measured is the time it takes the 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 x = Maximum speed attained (miles per hour) The simple linear model E(y) = Bo + Bjx was fit to the...
