Consider the cost information given in Exercise 9-30. Suppose that the process model represented by equation 9-31 is appropriate. It requires 2 h to investigate a false alarm, the profit per hour of operating in the in-control state is $500, and it costs $25 to eliminate the assign-

able cause. Evaluate the cost of the arbi-

trary control chart design n = 5, k = 3, and h = 1.
