A production line operates with a mean filling weight of 16 ounces per container. Overfill- ing or underfilling presents a serious problem and when detected requires the operator to shut down the production line to readjust the filling mechanism. From past data, a population standard deviation o = .8 ounces is assumed. A quality control inspector selects a sample of 30 items every hour and at that time makes the decision of whether to shut down the line for readiustment. The level of significance is a 05.
