Answer 9.20 9.20 Consider the situation of Exercise 9.11. Esti-mation of the mean diameter, while important, is notnearly as important as trying to pin down the loca-tion of the majority of the distribution of diameters.Find the 95% tolerance limits that contain 95% of thediameters. 9.11 A machine produces metal pieces that are cylin-drical in shape. A sample of pieces is taken, and thediameters are found to be 1.01, 0.97, 1.03, 1.04, 0.99,0.98, 0.99, 1.01, and 1.03 centimeters. Find a 99% con-fidence interval for the mean diameter of pieces fromthis machine, assuming an approximately normal dis-tribution.

Specifications for a metal shaft are much wider than the machine used to make the shafts is capableof. Consequently, the decision has been made to allow the cutting tool to wear a certain amountbefore replacement. The tool wears at the rate of .004 centimeter per piece. The process has a naturalvariation, σ, of .02 centimeter and is normally distributed. Specifications are 15.0 to 15.2 centimeters.A three-sigma cushion is set at each end to minimize the risk of output outside of the specifications.How many shafts can the process turn out before tool replacement becomes necessary?
