Question
Consider a double-sampling plan for which the size of the first sample is 30 while the size of
the second sample is 60. The lot is accepted after a first sample if the number of defectives is
at most 2. The lot will be rejected if the total number of defectives after the first or the
second sample is at least 5.
Assuming the number of defectives in the sample follow binomial distribution, calculate the
probability of acceptance, P(A), using MS excel when the proportion of defective items are p-0.02
and p=0.08 (correct the answer to four decimal places).
