A quality engineer is comparing five different processes used to manufacture the same product. All five processes have the same process capability index $($Cpl$),$ and the specification limits are identical: a lower specification limit $($LSL$)$ of $46$ and an upper specification limit $($USL$)$ of $88.$ However, each process has a different process mean.

Which one of the following processes is expected to have the best performance in terms of meeting specifications?

The one centered at $67$

The one centered at $74$

The one centered at $65$

They should all perform the same.

The one centered at $60$
