Problem 2 (20 points): The in-control mean of the inside diameter of an “O” ring is u=1.45 inches. The in-control standard deviation is o=0.001 inch. Assume the inside diameters are normally distributed. 1) What are the “3 sigma” (i.e., a = 0.0026) control limits of the X-bar chart, if sample size n = 6. 2) If the specification limits are 1.45 + 0.0011, find the proportion of rejected 'O’rings when the process is in control.
