9. The Canine Gourmet Company produces delicious dog treats for canines with discriminating tastes. Management sets up a process target so that when process is in control, the average weight per packet is 44.1 grams and the range in the weight of each sample is averaged at 6.1 grams. To ensure that the process is in control, an inspector periodically selects a random box of 10 packets and weighs each packet at the end of the filling line. (Hint: use process target, instead of using the data, when calculating the average weight and the range, as you are trying to inspect whether your current production meets the target or not) The results from the last 5 samples of 10 packets are: New Data Sample 12345 5 Weight 44 39 44 45 48 39 44 45 48 44 40 39 40 41 40 39 40 41 40 40 46 46 49 44 45 46 49 44 45 46 39 43 35 38 40 43 35 38 40 39 49 49 48 46 49 48 48 49 48 46 a.

Webster Chemical Company produces mastics and caulking for the construction industry. The product is blended in large mixers and then pumped into tubes and capped. Management is concerned about whether the filling process for tubes of caulking is in statistical control. The process should be centered on 8 ounces per tube. Several samples of eight tubes were taken, each tube was weighed, and the weights in Table were obtained.
