In a production system with an acceptable quality level of 0.01, production is made in batches of 500. If the inspection level is II and the inspection type is normal, what should be the acceptance plan that minimizes the total inspection? (5p) If none of the first 10 batches received in the acceptances made according to this plan were rejected, and if the total number of defective parts found in the inspections is 7, analyze and interpret whether the inspection type is changed, and if it is, what type of inspection is applied?
