a) Suppose lots of lightbulbs are created from a continuous production line process, such that a binomial distribution is appropriate for analyzing the sampling plan: Suppose that the sampling plan is to select 3 fuses and test them, with a lot being accepted if none are defective. Criticize this sampling plan. In particular, find the probability of accepting a lot that is 30% defective. b) For the above situation, suppose we include a RECTIFICATION step for rejected lots. Plot the...

We want to determine the AOQ for an acceptance sampling plan when the quality of the incoming lots in percent defective is 4%, and then again when the incoming percent defective is 8.5%. The sample size is 50 units for a lot size of 600 units. Furthermore, Pa at 4% defective levels is 0.89. At 8.5% incoming defective levels, the Pa is found to be 0.59. Determine the average outgoing quality for both incoming percent defective levels. The average outgoing...

29, A single sampling plan consists of: N. 1480. n iso, and c-2. If an incoming lot containing 2% non- conforming is inspected using this plan, the probability that this lot will be accepted is: a. 0.199 b. 0.224 c. 0.271 d. 0.423 e. 0.667 30. Using the acceptance sampling plan in question 29 above, the average total inspection would be about: a. 150 b. 563 С. 626 d. 713 e. 917 Probability of having less than two nonconforming parts...

1. Many companies use a incoming shipments of parts, raw materials, and so on. In the electronics industry, component parts are commonly shipped from suppliers in large lots. Inspection of a sample of n components can be viewed as the n trials of a binomial experimem. The outcome for each component tested (trialD will be that the component is classified as good or defective defective components in the lot do not exceed 1 %. Suppose a random sample of fiver...
