A double-sampling plan is usually less expensive than a single-sampling plan if the lot has a low number of defectives.

Question

Quizplus · Accepted Answer

This is true because a double-sampling plan involves inspecting the lot twice, with the second inspection only occurring if the first sample yields too many defectives. This means that if the first sample has a low number of defectives, the lot may be accepted without the need for a second inspection, thereby saving time and money compared to a single-sampling plan where a second inspection is always required.
