Copyright 2008 by Pearson Education, Inc. 252 CHAPTER SEVEN Sampling and Sampling Distributions Using Statistics @ Oxford Cereals Oxford Cereals fills thousands of boxes of cereal during an eighthour shift. As the plant operations manager, you are responsible for monitoring the amount of cereal placed in each box. To be consistent with package labeling, boxes should contain a mean of 368 grams of cereal. Because of the speed of the process, the cereal weight varies from box to box, causing some boxes to be underfilled and others overfilled. If the process is not working properly, the mean weight in the boxes could vary too much from the label weight of 368 grams to be acceptable. Because weighing every single box is too time-consuming, costly, and inefficient, you must take a sample of boxes. For each sample .
