This question and the following questions are given the same scenario below: A supplier ships a lot of 10000 parts to a customer. Assuming a double sampling plan is used to check the supplier’s product quality. For lot size N=10000, after the initial sampling (n1=100, c1=2, r1=5), they found it necessary to collect the second sample.
Question 23
How many nonconforming units are possibly in the first sample?
Option A ≤ 2
Option B ≥ 5
Option C > 2 & < 5
Option D none of the above correct
They decided to accept this lot after the second sampling (n2=150, c2=6, r2=7). Based on the described scenario, what is the maximum number of nonconforming units possibly found in the second sample?
Option A 1
Option B 2
Option C 3
Option D 4
