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 30 of the airline's pilots. The pilots in the sample, as of the end of last year, had a sample mean experience of 3214 hours with a sample standard deviation of 832 hours. The airline's document stated that, at the end of last year, the airline's pilots had a population mean experience of 3345 hours of flight with a population standard deviation of 767 hours. Fill in the blanks below with the proper notation for the population mean, the population standard deviation, the sample mean, and the sample standard deviation. Population mean: (Choose one) v = 3345 hours Population standard deviation: (Choose one) ▼ = 767 hours Sample mean: (Choose one) v = 3214 hours Sample standard deviation: (Choose one) v = 832 hours
