You may need to use the appropriate appendix table to answer this question. The average price for a gallon of gasoline in the country A is $2.76 and in country B it is $2.35. 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.) 0.0968 X
