6.61. One-pound coffee cans are filled by a machine, sealed, and then weighed automatically. After adjust- ing for the weight of the can, any package that weighs less than 16 oz is cut out of the conveyor. The weights of 25 successive cans are shown in Table 6E.20. Set up a moving range control chart and a control chart for individuals. Estimate the mean and standard devi- ation of the amount of coffee packed in each can. Is it reasonable to assume that can weight is normally distributed? If the process remains in control at this level, what percentage of cans will be underfilled?
