Capability Analysis DPMO: C&As potato chip filling process has a lower specification limit of 9.5 oz. and an upper specification of 10.5 oz. The standard deviation is 0.5 oz. and the mean is 10 oz. What will the standard deviation of the process need to be in order to achieve a defective ppm of 2700? What comes the closest?

Hint: Review the Process Capability slides or do a web search to determine what Cp value corresponds to a defective ppm of 2700. Then work backwards to determine what standard deviation will give you the desired Cp value and round it to the closest provided answer.

A.) 0.15

B.) 0.2

C.) 0.25

D.) 0.3

E.) None of the above is within 0.05 of correct answer

F.) Cannot be determined
