In determining small airplane gallons per hour ratings, it was found that the gallons per hour for the single engine model is normally distributed, with a mean of 8 gallons per hours and a standard deviation of 0.35 mpg. Suppose that the airplane manufacturer samples 9 planes from its assembly line and tests them for gallons per hour in flying conditions. If you but one plane which follow this distribution what is the probability that one plane will obtain a gallon per hour of more than 7.9 gallons per hour
