Textbook Question

Chapter 12.3, Problem 14EE

Automotive Trades In testing the acceleration from 0 to 60 mph for a certain automobile, the following times (in seconds) resulted from a series of trials:

6.8, 6.9, 6.8, 6.7, 6.8, 6.6, 6.9, 7.0, 6.7, 6.8, 6.6, 6.7, 7.1, 6.9, 6.5

(a) Calculate the mean and standard deviation of these times.
(b) What range of times should the technician report so the interval would normally contain approximately 68% of the actual times?
