Problem:
C-spec, Inc; is attempting to determine whether an existing machine is capable of milling an engine part that has a key specification of 2 t 0.004 inches. After a trial run on this machine, C C-Spec, Inc. Spec has determined that the machine has a sample mean of 2.001 inches with a standard deviation of 0.002 inch.
Calculate the Cpk for this machine.
Large-scale integrated (LSI) circuit chips are made in one department of an electronics firm. These chips are incorporated into analog device not particularly good for LSI manufacture, so the AQL specified by that department is 21% while the LTPD acceptable by the assembly depai to accept a consumer's risk of 10 percent and a producer's risk of 5 percent. Use Exhibit 10.16.
a. Find the sample size.
b. How would you tell someone to do the test?
