2. What is the probability of 4 nonconforming items in a sample, if the proportion nonconforming in the lot is 4%?

3.What is the probability of accepting a lot when a sample has 3 or less nonconforming items, if the proportion nonconforming in the lot is 1%?

4. What is the average outgoing quality limit

5. What is the average total inspection for incoming lots of 3%

6. What is the average sample number with a proportion nonconforming of 0.04

7. if the acceptable quality level is 3.1% what is the probability of rejecting an acceptable lot?
