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. 68.89 78.63 68.96 84.36 79.85 86.94 101.15 97.49 a 3 Click the icon to view the table of critical t-values. (a) Determine a point estimate for the population mean travel tax. Apoint estimate for the population mean travel tax is $ 83.28 . (Round to two decimal places as needed.) (b) Construct and interpret a 95% condence interval for the mean tax paid for a three-day business trip. Select the correct choice below and ll in the answer boxes to complete your choice. (Round to two decimal places as needed.) O A- One can be :I% condent that the mean travel tax for all cities is between $ and $ I. O 3- The travel tax is between $D and $|:| for D% of all cities. 0 c- One can be D% condent that the all cities have a travel tax between $D and $El. O 0- There is a :|% probability that the mean travel tax for all cities is between $| I and $
