At the end of last year, the legal arm of a large commercial airline issued a document that included statements about the flight experience of the airline's pilots (the total flying time per pilot). To check these statements, a federal watchdog organization examined the flight records of a random sample of 25 of the airline's pilots. The pilots in the sample, as of the end of last year, had a sample mean experience of 3375 hours with a sample standard deviation of 985 hours. The airline's document stated that, at the end of last year, the airline's pilots had a population mean experience of 3255 hours of flight with a population standard deviation of 875 hours. Fill in the blanks below with the proper notation for the population mean, the sample mean, and the sample standard deviation. Population mean: (Choose one) Sample mean: (Choose one) Sample standard deviation: (Choose one) ▼ -3255 hours -3375 hours =985 hours X S
