Quizplus · Accepted Answer

C_p is a capability index that measures the process capability based on the standard deviation and the specification limits. A value greater than 1 indicates that the process is capable of meeting the specification limits with a high degree of confidence. Specifically, if the process mean can be centred, then more than 99.73% of the observations will fall inside the specification limits, which corresponds to 3 standard deviations from the mean in both directions. Therefore, the statement is true.
