The average price for a gallon of gasoline in the United States is $3.73 and in Russia itis $3.40 (Bloomberg Businessweek, March 5–March 11, 2012). Assume these averagesare the population means in the two countries and that the probability distributions arenormally distributed with a standard deviation of $.25 in the United States and a standarddeviation of $.20 in Russia.a. what is the probability that a randomly selected gas station in the United Statescharges less than $3.50 per gallon?b. what percentage of the gas stations in Russia charge less than $3.50 per gallon?c. what is the probability that a randomly selected gas station in Russia charged morethan the mean price in the United States?
