Description
Use the data from the previous X-Bar & s assignment (See
below), and s-Bar/cy formula to convert the data back to
individuals and calculate 6 sigma, Cp, and Cpk. Sketch the
distribution and interpret the Cp, and Cpk indices (Explain
how the voice of process compares to the voice of the
customer). The specification limits are .0625 +/- 0.0005
(625 +/- 5 coded).
From Table B: n=5 (Observations or measures in a subgroup),
c4=.9400
X-Double-Bar = 626.6
s-Bar = 1.38
Cp = (USL - LSL)/ (6*sigma)
Cpk= MIN((USL-Process Center) or (Process Center -
LSL)}/(3*sigma)
