1. A simple sampling plan is stated as (100, 2). Accordingly, in
a batch of 5000 items purchased, a random sample of 100 was
inspected, and 2 were found to be defective. Now the decision is
to
reject the whole batch
accept the whole batch
reject the batch, but accept the 98 which are good
take another sample for inspection
2. A purchase policy is to apply (20,1) sampling plan to
an incoming batch of products. Say the batch has 1000 items, and 49
of them are defective. What is the probability that the batch would
be accepted?

fraction)
