A very large ba(tch of components has arrived at a distributor. The batch can be characterized as accept able only if the proportion of defective components is at most.10. The distributor decides to randomly select 10 components and to accept the batch only if the number of defective components in the sample is at most 2. a. What is the probability that the batch will be accepted when the actual proportion of defectives is .01? .05? .10? .20? .25? b. Let p denote the actual proportion of defectives in the batch. A graph of P(batch is accepted) as a function of p, with p on the horizontal axis and P(batch is accepted) on the vertical axis, is called the operating characterstics curve for the acceptance sampling plan. Use the results of part (a) to sketch this curve for 0<p<1. c. Repeat parts (a) and (b) with "1" replacing "2" in the acceptance sampling plan. d. Repeat parts (a) and (b) with "15" and replacing "10" in the acceptance sampling plan. e. Which of three sampling plans, that of part (a), (c), (d), appears most satisfactory, and why?
