Quizplus · Accepted Answer

According to the table I.1, at n=20 and c=2, the corresponding letter code is K, which has acceptance number of 0 and rejection number of 2. 
The producer's risk is the probability of rejecting a lot when the true proportion of defectives in the lot is equal to AQL. From the table, the probability of accepting a lot at AQL is 0.495. Therefore, the producer's risk is 1 - 0.495 = 0.505, which is between 0.0001 and 0.01. Hence, the correct answer is A.

-The Quality Manager Has Fixed N = 20 and C
