An acceptance sampling plan has lots of 500 pieces and a sample size of 60. The number of defects in the sample may not exceed 2. This plan, based on an OC curve, has a probability of 0.57 (57%) of accepting lots when the incoming lots have a defective rate of 3.0%, which is the historical average of the process. For the customers, the average outgoing quality = ____% (enter your response as a percentage rounded to two decimal places).

1. You are conducting QC inspection of packaged pharma product for attributes (appearance) using single sampling plan K at AQL level 1.0%. The batch size is 3,000 units. The plan requires you to sample 125 units and accept the batch if you find 3 or fewer defective units, and reject the batch if you find 4 or more defectives. The OC curve for that sampling plan is shown below After reviewing the records for the last 100 batches produced you discover that QC rejected 25 of those batches Assuming that quality of all batches is about the same, how many defective units should you expect to find on average in every batch

We want to determine the AOQ for an acceptance sampling plan when the quality of the incoming lots in percent defective is 4.5%, and then again when the incoming percent defective is 7%. The sample size is 100 units for a lot size of 600 units. Furthermore, Pa at 4.5% defective levels is 0.85. At 7% incoming defective levels, the Pa is found to be 0.43. Determine the average outgoing quality for both incoming percent defective levels. The average outgoing quality for 4.5% incoming percent defective level is nothing. (Round your response to three decimal places.)
