A travel agency is concerned with the accuracy and appearance of itineraries prepared for its clients. Defects can include errors in times, airlines, flight numbers, prices, car rental information, lodging, charge card numbers, and reservation numbers, as well as typographical errors.

If your answer for LCL is negative, enter this value as 0.) b. A client scheduled a trip to Dallas. Her itinerary contained six errors. Interpret this information. OA. The number of defects is less then the lower control limit, so the process is not in control. OB. The number of defects is greater than the upper control limit, so the process is not in control. OC. The number of defects is within the control limits, so it is assumed that the process is not in control. OD. The number of defects is within the control limits, so it is assumed that the process is in control.
