I need to calculate sample sizes and ALQ for attribute sampling. The client wants 95.5% correct. Batch sizes vary from 300 - 200,000, and there is no historical data. I'm new to this and used MIL-STD 105E to work thorough an example. I used batch size 2500, Inspection Level II, ALQ of 4. Sample size of 125 is indicated, but the Ac is 10, which is 8%, not the 4% I thought it would be. Could someone tell me what am I missing? The OC curve?
