West Battery Corp. has recently been receiving complaints from retailers that its 9-volt batteries are not lasting as long as other name brands. James West, head of the TQM program at
West's Austin plant, believes there is no problem because his batteries have had an average life of 60 hours, about 10% longer than competitors' models. To raise the lifetime above this
level would require a new level of technology not available to West. Nevertheless, he is concerned enough to set up hourly assembly line checks. Previously, after ensuring that the
process was running properly, West took samples of 5 9-volt batteries for 25 test to establish the standards for control chart limits. Those 25 tests are shown in the following table:

Canine Gourmet Super Breath dog treats are sold in boxes labeled with a net weight of 9 ounces (255grams) per box. Each box contains 6 individual 1.5-ounce packets. To reduce the chances of shorting thecustomer, product design specifications call for the packet-filling process average to be set at 43.0 grams so that the average net weight per box of 6 packets will be 258 grams. Tolerances are set for the box to weigh 258±12 grams. The standard deviation for the packet-filling process is 1.01 grams. The target process capability ratio is 1.33. One day, the packet-filling process average weight drifts down to 42.5 grams. Is the packaging process capable? Is an adjustment needed? Since the process capability index, Cpk,is ?,the process is capable?is not capable?

- The National Bank of Warwick is concerned with com-plaints from customers about its drive-through window op-eration. Customers complain that it sometimes takes too long to be served and since there are often cars in front and back of a customer, they cannot leave if the service is tak-ing a long time. To correct this problem the bank installed an intercom system so the drive-through window teller cancall for assistance if the line backs up or a customer has an unusually long transaction. The bank’s objective is an aver-age customer’s waiting and service time of approximately 3 minutes. The bank’s operations manager wants to moni-tor the new drive-through window system with SPC. The manager has timed five customers’ waiting and servicetimes at random for 12 days as follows:Develop an -chart to be used in conjunction with anR-chart to monitor this drive-through window process andindicate if the process is in control using these charts.
