You may need to use the appropriate appendix table to answer this question. distributions are normally distributed with a standard deviation of \( \$ 0.25 \) in the Country \( \mathrm{A} \) and a standard deviation of \( \$ 0.20 \) in Country \( \mathrm{B} \). (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.) \( \% \)
