Note: Chicago has the highest travel taxes in the country at $101.27. In Problem 32 from Section 9.2, it was verified that the data are normally distributed and that s = 12.324 dollars. Construct and interpret a 90% confidence interval for the standard deviation travel tax for a 3-day business trip.
