Question

Scratch and dent An appliance manufacturer stock-
piles washers and dryers in a very large warehouse for

shipment to retail stores. Sometimes in handling them
the appliances get damaged. Even though the damage
may be minor, the company must sell those machines at
drastically reduced prices. The company goal is to keep
the level of damaged machines below 2%. One day an
inspector randomly checks 60 washers and finds that 5 of
them have scratches or dents. Is this strong evidence that
the warehouse is failing to meet the company goal? Test
an appropriate hypothesis and state your conclusion. Be

sure the appropriate assumptions and conditions are satis-
fied before you proceed.
