An air transport association surveys business travelers to develop quality ratings for transatlantic gateway airports. The maximum possible rating is 10. Suppose a simple random sample of 50 business travelers is selected and each traveler is asked to provide a rating for a certain airport. The ratings obtained from the sample of 50 business travelers follow.
6 | 4 | 5 | 8 | 7 | 6 | 6 | 3 | 3 | 8 |
10 | 4 | 8 | 7 | 8 | 7 | 5 | 9 | 4 | 8 |
4 | 3 | 8 | 5 | 6 | 4 | 4 | 4 | 8 | 4 |
5 | 7 | 2 | 5 | 9 | 9 | 8 | 4 | 8 | 9 |
9 | 5 | 9 | 7 | 8 | 3 | 10 | 8 | 9 | 6 |
Develop a 95% confidence interval estimate of the population mean rating for this airport. (Round your answers to two decimal places.)
