The Grand Marriott Hotelis a large mid-range hotel in Miami. Part of its quality management practices is to inspect guest rooms immediately after house staff have finished cleaning. A sample of 50 rooms are inspected each day. Besides providing housing staff with individual service quality and productivity reports, quality assurance inspectors maintain an overall count of the number of rooms designated as unacceptable each day. The numbers of unacceptable rooms over a recent two week, 14 day period are indicated below.
