Question:
A lot of 3500 books arrives at a bookstore. To check if the entire lot is acceptable, a first random sample of n1 = 150 books is taken from the lot and if c1 = 1 or less of the books are found to be defective, the entire lot is accepted; if greater than c2 = 5 books are found, the lot is rejected. If between 2 and 4 books are found to be defective on the first sample, a second sample is taken of n2 = 100 books and if the combined number of defects of the first and second samples is less than c2 = 5, the lot is accepted and rejected otherwise. (a)Probability of acceptance, first sample (b)Probability of rejection, first sample (c)Probability of acceptance, second sample (d)Probability of acceptance, combined sample
