c. If the process is not capable, what percent of the output will fall outside the specification limits?

(Hint:Use the normal distribution.)

Factors for calculating three-sigma limits for the x-chart and R-chart.

The central line of the chart for the sample means is set at 8.30 and for the mean range at 0.23 mm. The process is in control, as established by samples of size 6. The upper and lower specifications for the diameter of the rollers are (8.30 +0.25) and (8.30 -0.25) mm, respectively.
