Consider the double sampling plan for Spire CDs described in this section. Over a period of one year, 3,860 boxes of records are subject to inspection using this plan.

If 60 percent of these batches are “good” (that is, in 60 percent of the batches the proportion of defectives is exactly 10 percent) and 40 percent are “bad” (that is, in 40 percent of the batches the proportion of defectives is exactly 30 percent), then what is the expected number of batches

a. Accepted?

b. Rejected?

c. Accepted on the first sample?

d. Accepted on the second sample?

e. Rejected on the first sample?

f. Rejected on the second sample?
