The worksheet is open and shows the data we used in the process control
The data is filtered to only the phase when the process was-in control
The 6-up capability analysis shows the process control charts, a histogram of the
distribution, a box-plot summary of the distribution, a mean +/- 3 sigma plot, and
normal probability plot. Upper and lower specification limits show the
