4.68 Lot inspection sampling. Imagine you are purchasing small
lots of a manufactured product. If it is very costly to test a
single item, it may be desirable to test a sample of items from the
lot instead of testing every item in the lot. Suppose each lot
contains 10 items. You decide to sample 4 items per lot and reject
the lot if you observe 1 or more defective. a. If the lot contains
1 defective item, what is...
