# Question

You have been told that the distribution of regular unleaded gasoline prices over all gas stations in Indiana is normally distributed with mean \$2.95 and standard deviation \$0.075, and you have been asked to find two dollar values such that 95% of all gas stations charge somewhere between these two values. Why is each of the following an acceptable answer: between \$2.776 and \$3.081, or between \$2.803 and \$3.097?
Can you find any other acceptable answers? Which of the many possible answers would you give if you are asked to obtain the shortest interval?
