Question

A shift of the process mean from the centerline, measured in number of sigmas of the
process, equal to 2.8*sigma, will generally be considered to be a small shift because it
is less than L=3.
True
False

Expert Solution

Step 1

A shift from the centerline from a center line is measured using the $σ$ -limits.

For a process to be in control, generally the 3- $σ$ limits are taken.
