Some sources advocate a somewhat more restrictive type of doubling-sampling plan in which r1 = c2 + 1; that is, the lot is rejected if at either stage the (total) number of defectives is at least r1 (see the book by Montgomery). Consider this type of sampling plan with n1 = 50, n2 = 100, c1 = 1, and r1 = 4. Calculate the probability of lot acceptance when p = .02, .05, and .10.
