A supermarket buys oranges from a certain company, that claims that the fraction of unacceptable fruit (e.g., rotten) in each shipment does not exceed 3%. The supermarket is willing to accept such (but not higher) percentage of bad fruit. The procedure agreed upon specifies that a random sample of 30 oranges will be selected from each shipment (the method of sampling is typically also a part of the protocol).
