The Metro Packaging Company in Richmond produces clear plastic bottles for the Kooler Cola Company, a soft-drink manufacturer. Metro inspects each lot of 5000 bottles before they are shipped to the Kooler Company. The soft-drink company has specified an acceptable quality level of 0.06 and a lot tolerance percent defective of 0.12. Metro currently has a sampling plan with n = 150 and c ≤ 4. The two companies have recently agreed that the sampling plan should have a producer’s risk of 0.05 and a consumer’s risk of 0.10. Will the current sampling plan used by Metro achieve these levels of α and β?
