inside diameter of the bearing, with only the last three
decimals recorded (i.e., 34.5 should be 0.50345).
(a) Set up ī and R charts on this process. Does the
process seem to be in statistical control? If nec-
essary, revise the trial control limits.
(b) If specifications on this diameter are 0.5030 ±
0.0010, find the percentage of nonconforming
bearings produced by this process. Assume that
diameter is normally distributed.
