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.
a. Find a 99% prediction interval for the breaking torque of a single boll.
b. Find a tolerance interval for the breaking torque that includes 95% of the bolts with 99% confidence.
