Piston rings for an automotive engine are produced by a forging process.We monitor the inside diameter of the rings manufactured by this process using an and an s control chart.Samples of size 4 are taken at regular intervals,and the sample means and standard deviations are computed and plotted on the charts in time order.The overall mean of the sample means is
= 73.97 millimeters,and the sample standard deviation of all measurements is s = 0.03 millimeters.Specifications call for the inside diameter of the rings to be 74.00 ± 0.10 millimeters.The control chart constants are (partially) reproduced below. What is the value of an estimate of the capability index Cp?
A) 0.72
B) 0.78
C) 1.02
D) 1.11
