A metal fabricator produces metal rods with an outer diameter
that has a 3.250 ±.01 inches specification. A machine operator
takes several sample measurements over time and determines the
sample mean outer diameter to be 3.251 inches with a standard
deviation of .002 inches.
Calculate the process capability index for this example.
