Question

C&A's potato chip filling process has a lower specification limit of 9.5 oz. and an upper specification limit of 105 oz. The standard deviation is 03 oz. and the mean is 10 oz. What is the process capability index for the chip filling process?

Answer 1

Process capability index (cp) for the chip filling process is 0.56

Step-by-step explanation:

Process capability index (cp) = (Upper Specification Limit - Mean) / (3 * standard deviation) = (Mean - Lower Specification) / (3 * standard deviation)

Process capability index (cp) = (10.5 - 10) / (3*0.3)

Process capability index (cp) = 5/9

Process capability index (cp) = 0.56
