C-Spec, Inc. is attempting to determine whether an existingmachine is 3 sigma capable of milling an engine part that has a keyspecification of 3 ± 0.05 inches. After a trial run on thismachine, C-Spec has found that the machine has a sample mean of3.001 inches with a standard deviation of 0.030 inch.
a). Calculate the Cpk for this machine. (Round your answer to 3decimal places)
b). What would be the defect rate if the machine is used inproduction? (Round your answer to 2 decimal places)
