Travelers pay taxes for flying, car rentals, and hotels. The following data represent the total travel tax for a 3-day business trip in eight randomly selected cities. The data have already been verified to be normally distributed and that the standard deviation, s, is 12.324 dollars. Construct and interpret a 90% confidence interval for the standard deviation travel tax for a 3-day business trip by answering the following: 2A) Find the variance. 2B) Describe what you are looking up on Table VIII to find X ( α 2 ) 2 and X ( 1 − α 2 ) 2 2C) Find the lower & upper bound. 2D) Describe what this information means that you have found for this problem, as in, interpret the information.
