1. In the sampling plan example1 one important issue is to determine the cut-off value 'a'. The following two additional conditions are provided. (i) We think that the lot is of high quality,r if p = [1.0-5 (5% defectives). (ii) A lot having :0 = 0.1 (10% defectives) is of low quality. Suppose n 2 90. By accounting for the Chance of making some wrong decisions, outline a method using binomial distribution to determine the cut-off. Do you think it is preferable to use a sample size of n : 100 to conduct the sampling plan? Explain
