Question #5 Part B

Extracted text: 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. 67.82 78.08 69.71 83.48 79.56 87.13 100.69 99.76 Click the icon to view the table of critical t-values. (a) Determine a point estimate for the population mean travel tax. A point estimate for the population mean travel tax is $ 83.28 . (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. There is a % probability that the mean travel tax for all cities is between $ and $ B. One can be % confident that the mean travel tax for all cities is between $ and $ C. The travel tax is between $ and $ for % of all cities. D. One can be % confident that the all cities have a travel tax between $ and $
