Suppose that the average price for a gallon of gasoline in the Country A is $2.74 and in Country B it is $2.40. Assume these averages are the population means in the two countries and that the probability distributions are normally distributed with a standard deviation of $0.25 in the Country A and a standard deviation of $0.20 in Country B. a.) What is the probability that a randomly selected gas station in Country A charges less than $2.50 per gallon? (Round your answer to four decimal places.) b.) What percentage of the gas stations in Country B charge less than $2.50 per gallon? (Round your answer to two decimal places.) c.) What is the probability that a randomly selected gas station in Country B charged more than the mean price in the Country A? (Round your answer to four decimal places.)
