Question 508918
With one method of the procedure called acceptance sampling, a sample of items is randomly selected without replacement, and the entire batch is rejected if there is at least one defect. 
------------------------
The Newport Gauge Company has just manufactured a batch of aircraft altimeters and 3% are defective. 
Question: If the batch contains 4000 altimeters and 100 of them are selected without replacement and tested, what is the probability that the entire batch will be rejected?
---
P(reject) = P(>=1 defect in 100) 
= 1 - P(no defects in 100)
= 1 - (0.97)^100 
= 1 - 0.0476 
= 0.9524
