The relationship for process capability index is: Upper C Subscript pk Baseline equals min left parenthesis StartFraction Upper specification limit minus x overbar Over 3 sigma EndFraction comma StartFraction x overbar minus Lower specification limit Over 3 sigma EndFraction right parenthesis For the given information, the process capability index (Upper C Subscript pk ) = 0.83 (round your response to two decimal places). Part 4 A Upper C Subscript pk index of 1.0 for both the upper and lower control limits indicates that the process variation is centered within the upper and lower control limits. As the Upper C Subscript pk index goes above 1.0, the process becomes increasingly target-oriented with fewer defects. If the Upper C Subscript pk is less than 1.0, the process will not produce within the specified tolerance. Based on the process capability index (Upper C Subscript pk ) for the given information, one can say that the process the specification
