A) Acceptance sampling involves testing a sample from a population, and making a decision based on the results. If the sample is good enough, the entire population is accepted, and if the sample is poor enough, the entire population is rejected.

B) The sampling plan outlines the sample size to be drawn, along with the critical acceptance and rejection numbers. These numbers are used to determine whether to accept or reject the entire population based on the results of the sample.

C) The operating characteristic curve shows the relationship between the quality of the population and the probability of accepting or rejecting it. A steeper curve means that the sampling plan is better at discriminating between good and bad lots.

All of these statements are true, so the correct answer is D.
