The specification for the diameters of ball bearings is

Chapter 10, Problem 2E

(choose chapter or problem)

The specification for the diameters of ball bearings is 15.40–15.60 mm. Data from an \(\overline{X}\) chart, based on samples of size 8, that shows that the process is in control, yield values of \(\overline{\overline{X}}=15.52\) and \(\overline{R}=0.05\).

a. Compute the value of \(C_{pk}\) for this process.

b. Is the process capability acceptable? Explain.
