A process that produced cereal-crunch single-serve snacks routinely takes samples of size 6 to inspect the weights of the snacks for control. The process variability is currently in control and the process standard deviation is known to be 0.22 ounces. The most recent 40 samples showed a mean sample average weight of 8.1 ounces. A quality control manager is looking at the most recent sample of 6 snacks whose individual weights in ounces were: 7.9 7.9 8.1 8.5 7.9 8.0 (a) Compute the upper control limit for a control chart meant to check if the process mean weights are in control at 99.73% confidence level. Give 3 decimals. (b) Would this most recent sample cause the process mean to be tagged as out-of-control? Explain. (c) Suggest the next step in the quality control process.
