Abstract
Acceptance Sampling is a Statistical tool of Quality Control. Sampling plans are used to accept/reject the lots when inspecting a series of lots. In this paper an attempt is made to determine the cumulative probabilities of a Double sampling plan for various np values under the condition n₁=n₂ and acceptance number (c₁,c₂) with Poisson distribution as a base line distribution. Tables are constructed and numerical illustrations are given to describe the determination of cumulative Double Sampling Plan using Poisson distribution and its Operating Characteristic curve is drawn.
