Question

Quizplus · Accepted Answer

Double-sampling plans involve taking two samples - a smaller preliminary sample and a larger main sample. The preliminary sample is used to make an initial decision about acceptance or rejection, while the main sample is used to confirm or correct the decision made on the basis of the preliminary sample. Therefore, options A and B are both correct, while option C is incorrect. Option D is incorrect because it implies that any decision can be made after one sample, which is not true for double-sampling plans.
