hence, partial or complete activation of the Sy Such syringes tacked at a longer-than-desired length (4.980 inches or longer), the tacking is incomplete or inadequate, which can lead to cap loss and a potential cartridge loss in shipment and handling. Such syringes can be reworked manually to attach the cap at a lower position. However, this process requires a 100% inspection of the tacked syringes and results in in creased cost for the items. This final production step seemed to be producing more and more scrap and reworked syringes over successive weeks file Customer Support Survey. Use whatever Excel charts and descriptive statistics you deem appropri te to convey the information in these sample data and write a report to the manager explaining your must then be scrapped. If the cap is findings and conclusions 38. A Midwest pharmaceutical company manufactures ndividual syringes with a self-contained, single dose of an injectable drug. In the manufactur ing process, sterile liquid drug is poured into glass syringes and sealed with a rubber stopper. The re- maining stage involves insertion of the cartridge into plastic syringes and the electrical "tacking" of the containment cap at a precisely determined length of the syringe. A cap that is tacked at a shorter-than-desired length (less than 4.920 inches) leads to pressure on the cartridge stopper and The Excel file Syringe Samples provides sam- ples taken every 15 minutes from the manufacturing process. Develop control limits using the data and use statistical thinking ideas to draw conclusions.
