The Canine Gourmet Company produces delicious dog treats for canines withdiscriminating tastes. Management wants the box-filling line to be set so that the processaverage weight per packet is 45 grams. To make sure that the process is in control, aninspector at the end of the filling line periodically selects a random box of 10 packets andweighs each packet. When the process is in control, the range in the weight of eachsample has averaged 6 grams.a. Design an R- and an e-chart for this process.b.

At Quick Car Wash, the wash process is advertised to take less than 6 minutes. Consequently, management has set a target average of 320 seconds for the wash process. Suppose the average range for a sample of 10 cars is 10 seconds. Use the accompanying table to establish control limits for sample means and ranges for the car wash process.
The output of a certain integrated-circuit productionline is checked daily by inspecting a sample of 100 units.Over a long period of time, the process has maintaineda yield of 80 percent, that is, a proportion defective of 20 percent, and the variation of the proportion defec-tive from day to day is measured by a standard devi-ation of 0.04. If on a certain day the sample contains 38 defectives, find the mean of the posterior distribu-tion of as an estimate of that day’s proportion defec-tive. Assume that the prior distribution of Θ is a beta distribution.
