MIL-STD-105E standard was followed to inspect items submitted for inspection in lots of size 600. The general inspection level is level II and AQL is 0.65% nonconforming for single sampling plans. Following the standard, reduced inspection was used for inspecting Lot 11. Inspection results for Lot 11 to Lot 22 were available as shown in the following table. The MIL-STD-105E switching rules are given in the formula sheet. With reference to the given rules and charts, answer the following question: What sampling plans (sample size, rejection and acceptance numbers) was used for inspecting Lot 11? What sampling plans should be used for inspecting Lots 12, 13, 14, 18, and 23? Briefly discuss the differences between the MIL-STD-105E sampling system and LTPD based sampling plans.
