With one method of a procedure called acceptance sampling, a
sample of items is randomly selected without replacement and the
entire batch is accepted if every item in the sample is okay. A
company has just manufactured 967 CDs, and 88 are defective. If 3
of these CDs are randomly selcted for testing, what is the
probability that the entire batch will be accepted? Does this
outcome suggest that the entire batch consists of good CDs? Why or
Why not?...
