| A simple two-state cost investigation model calls for a decision to investigate if the following inequality holds: L(1 - P) > I + C(1 - P) If: L = excess operating cost if out of control P = probability that the process is in control I = cost of investigation C = cost of correction if out of control The value (1 - P) must be B. The inverse of the probability matrix. C. The probability that the process is out of control. D. The transpose of the probability matrix. |
