Question

Problem 14.70. In a production process the articles are packed in batches of 50 units. There is a sampling plan in which 10 items are randomly taken from each lot and the lot is accepted if there is no defect in the sample of 10.

1) If we get a batch of 50 units that contains 2 defective items. What is the probability of accepting that lot, following the defined sampling plan?

2) If it is important to the company that acceptance of batches with defective units is an exception, do you think the described sampling plan is reasonable? Explain.
