Question

1.     T F Double sampling is sometimes done when the first sample does not results in an acceptance

2.     T F The AOQL plot determines the percentage of defectives that are accepted over time

3.     T F The dominance of an action is determined by comparing the gain from that action due to each possible state of the world

4.     T F The percentage of defectives in a process has little impact on the average run length

5.     T F The posterior continuous distribution is partially a function of the prior distribution’s average

Answer 1

1. True, if the results of the first sample are not conclusive with regard to accepting or rejecting, a second sample is taken.
2. False, Average Outgoing Quality (AOQ) plot represents the relationship between the quality of incoming and outgoing materials.
3. True.
4. False,  The average run length (ARL) is the number of samples that will be observed, on average, before a point plots outside the control limits. So the percentage of defectives will impact ARL.
5. True.
