Question: Consider the suspension rod diameter data in Exercise 8-38. Compute a 95% tolerance interval on the diameter of the rods described that has 90% confidence.

Consider the suspension rod diameter data in Exercise 8-38.

Compute a 95% tolerance interval on the diameter of the rods described that has 90% confidence. Compare the length of the tolerance interval with the length of the 95% CI on the population mean. Which interval is shorter? Discuss the dif- ference in interpretation of these two intervals.
