Thirty percent of items produced by a particular company are actually defective. Each item produced is inspected, and the inspector stamps each item as either “good” or “bad”. The inspector incorrectly stamps a defective item as good 10% of the time. The inspector incorrectly stamps a non-defective item as bad 15% of the time. a) What proportion of items will be incorrectly classified? (show work with full probability statements) b) A customer has been sent an item that the inspector has concluded is “good”. What is the probability that it is really a defective item? (show all work with probability statements)

Problem 2. The Hit-and-Miss Manufacturing Company produces items that have a probability p of being defective. These items are produced in lots of 150. Past experience indicates that p for an entire lot is either 0.05 or 0.25. Furthermore, in 90 percent of the lots produced, p equals 0.05 (so p equals 0.25 in 10 percent of the lots). These items are then used in an assembly and ultimately their quality is determined before the final assembly leaves the plant....
