11. Plastic strips that are used in a sensitive electronic device are manufactured to a maximum specification of 305.70 mm (approximately 12 in.) and a minimum specification of 304.55 mm. If the strips are less than the minimum specification, they are scrapped; if they are greater than the maximum specification, they are reworked. The part dimensions are normally distributed with a population mean of 305.20 mm and a standard deviation of 0.25 mm. What percentage of the product is scrap? What percentage is rework? How can the process be centered to eliminate all but 0.1% of the scrap? What is the rework percentage now?
