Question 875392: Tanker trucks are designed to carry huge quantities of gasoline from refineries to filling stations. A factory that manufactures the tank of the trucks claims to manufacture tanks with a capacity of 8550 gallons of gasoline. The actual capacity of the tanks is normally distributed with mean mu = 8544 gallons and standard deviation sigma = 12 gallons.
What is the probability that a randomly selected tank will have a capacity of less than 8550 gallons? Round your answer to three decimal places

You can put this solution on YOUR website!
mu = 8544 gallons and standard deviation sigma = 12 gallons.
What is the probability that a randomly selected tank will have a capacity of less than 8550 gallons?
z = 6/12 = .5
P(z < .5) = .6915 0r 69.15% chance of less than 8500 gal capacity
