Question

Quizplus · Accepted Answer

Single sampling plan is a method of sampling inspection used for inspection of products or materials in which a random sample is drawn from each lot for testing. This method is widely used in quality control to determine whether a lot should be accepted or rejected based on the results of the sample. Option A is incorrect because the sample should be random, not non-random. Option C is not complete because it only addresses the situation when the first sample is inconclusive. The principle behind the single sampling plan is that a lot is either accepted or rejected based on a single sample, so option D is incorrect. Finally, option E is incorrect because a single sampling plan can be used repeatedly for inspection of multiple lots.
