Question: The data shown in Table 6E 2 are x and R

The data shown in Table 6E.2 are x and R values for 24 samples of size n = 5 taken from a process producing bearings. The measurements are made on the inside diameter of the bearing, with only the last three decimals recorded (i.e., 34.5 should be 0.50345).
(a) Set up x and R charts on this process. Does the process seem to be in statistical control? If necessary, revise the trial control limits.
(b) pˆ Pr{x  LSL} Pr{x  USL}  Pr{x  20} Pr{x  40}  Pr{x  20}  1Pr{x  40}
