Question 723650: A particular type of gasoline tank for a compact car is designed to hold 15 gallons. Suppose the actual tank capacity is normally distributed with mean of 15 gallons and standard deviation 0.2 gallons. The probability that a randomly selected tank will hold between 15.1 and 15.3 gallons is?
A particular type of gasoline tank for a compact car is designed to hold 15 gallons. Suppose the actual tank capacity is normally distributed with mean of 15 gallons and standard deviation 0.2 gallons. If a car with this gas tank gets exactly 25 mpg, what is the probability that the car can travel 370 miles without refueling?
