The braking distances of a sample of Ford F-150's are normally distributed. On a dry surface, the mean breaking distance was 158 feet and the standard deviation was 6.51 feet. What is the longest braking distance on a dry surface one of these Ford F-150's could have and still be in the best 1%?
Shade the bell curve, use the z-table to find the z-score that corresponds to 1% and convert the z-score back to the actual number.
