A gasoline tank for a Honda Accord is engineered to hold 15 gallons of gas. Gas tank capacity for a randomly selected Accord has an approximately normal distribution with mean 15.0 gallons and standard deviation of 0.1 gallons. (a) What is the probability that a randomly selected Accord has a gas tank capacity within one standard deviation of the mean? (b) What is the probability that a randomly selected tank will hold at most 14.85 gallons? Sketch a graph of this situation and shade the appropriate region.
