Chapter 5, Problem 2E(choose chapter or problem)
In a sample of 20 bolts, the average breaking torque was 89.7 J with a standard deviation of 8.2 J. Assume that the breaking torques are normally distributed.
Find a 99% prediction interval for the breaking torque of a single bolt. Find a tolerance interval for the breaking torque that includes 95% of the bolts with 99% confidence.
