a. What are p0, p1, n, and c for this problem?
Given information:
The population lot size is 1000 and the sample size is 50.
(a)
From the given question, the producer is like to have a 1% rate of defective.
The acceptable quality level or will be,
So, the value of is 0.01.
As the producer will reject a lot if the number of defectives is 4% or more. So, the lot tolerance percent defective or will be,
