Suppose that the average price for a gallon of gasoline in the United States is $3.75 and in Russia it is $3.38. 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 United States and a standard deviation of $0.20 in Russia a. What is the probability that a randomly selected gas station in the United States charges less than $3.65 per gallon (to 4 decimals)? b. What percentage of the gas stations in Russia charge less than $3.65 per gallon (to 2 decimals)? % c. What is the probability that a randomly selected gas station in Russia charged more than the mean price in the United States (to 4 decimals)? 0.0322
