Let's say an operations specialist has measured the estimated standard deviation of all parts for a process to be 00025321374 for five observation periods. That is to say, the estimated standard deviation for this sample of measurements is 0001306478. The Xdouble-bar, or average across averages, is 57.258. a) What is the upper control limit (UCL) for this sample that will keep this process within control? (Tips: 3 standard deviation right from the X double bar) (2pts)
