True or False: C_p 1 indicates that if the process average can be centered,then more than 99.73% of the observations will fall inside the specification limits.

Question

True or False: C_p > 1 indicates that if the process average can be centered,then more than 99.73% of the observations will fall inside the specification limits.

Quizplus · Accepted Answer

C_p > 1 is the formula for the process performance index (Ppk), which indicates the capability of a process to meet the specification limits. A Ppk value greater than 1 means that the process is capable of producing within the specification limits and if the process average can be centered, then more than 99.73% of the observations will fall inside the specification limits.
