Suppose that you are an ammunition manufacturer and that your manufacturing process yields a true % of defects of 2.5%. The probability of accepting a lot of 40,000 cartridges for a sample of 3000 with 15 defects is 85%. The AOQ for this set of 40,000 cartridges is
1. Suppose that you are an ammunition manufacturer and that your manufacturing process yields a true % of defects of 2.5%. The probability of accepting a lot of 40,000 cartridges for a sample of 3000 with 15 defects is 85%. The AOQ for this set of 40,000 cartridges is _____ %.
2. You are the process improvement manager and have just purchased a metal sheet roller to form gasket material for high-performance engines. You are excited because the company's goal is 6 sigma (no more than 3.4 defects per million) and this machine may be the innovation that you need. The gaskets cannot be more than 0.0002 in from the required thickness of 0.025 in. You want to know if you should replace the existing roller that has a Cpk = 1.0. The new sheet roller has a Cpk = ___. Round the answer to 2 decimal places.
