Two Processes (A\& B) are studied for machining a part. Process A produces parts which have a mean length of 150(in) and a standard deviation of 3 . Process B produces parts which have a mean length of 155(in) and standard deviation of 1 . The design specifications for the part are 150±10 (in). Data given is for Z=−3.333 area under the standard normal curve to the left of Z will be 0.00043. What will be the value of process capability ratio (Cp) for process B and (Cpk) for process A ?
