Chapter 17, Problem 17.6(choose chapter or problem)
Consider an in-control process with mean = 25 and =1 .0. Suppose that subgroups of size 5 are used with control limits 3/n, and centerline at . Suppose that a shift occurs in the mean, and the new mean is = 26 .5. (a) What is the average number of samples required (following the shift) to detect the out-of-control situation? (b) What is the standard deviation of the number of runs required?
