The accompanying data represent the total travel tax (in dollars) for a 3-day business trip in 8 randomly selected cities. A normal probability plot suggests the data could come from a population that is normally distributed. A boxplot indicates there are no outliers. Complete parts (a) through (c) below. 69.84 79.24 70.51 82.04 80.89 87.66 100.06 97.78 (a) Determine a point estimate for the population mean travel tax. A point estimate for the population mean travel tax is $ (Round to two decimal places as needed.) (b) Construct and interpret a 95% confidence interval for the mean tax paid for a three-day business trip. Select the correct choice below and fill in the answer boxes to complete your choice. (Round to two decimal places as needed.) O A. The travel tax is between S and S for % of all cities OB. One can be % confident that the mean travel tax for all cities is between $ and $ OC. There is a % probability that the mean travel tax for all cities is between and S OD. One can be % confident that all cities have a travel tax between S and S (c) What would you recommend to a researcher who wants to increase the precision of the interval, but does not have access to additional data? The researcher could V the
