The Lundberg Survey monitors gas prices at gas stations nationwide. In a recent month, Lundberg reported that the average regular gas price for the stations it surveyed was $3.40 per gallon. Assume the population distribution of gas prices is normal. The sample size was 24 stations. Because the population standard deviation is unknown, the researchers calculated a sample standard deviation of $.14. Please build a 90% confidence interval estimate of the average price of a gallon of gas for the population of gas stations nationwide. Please round your final answer to the nearest penny.
