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 of50 businesstravelers is selected and each traveler is asked to provide a rating for a certain airport. The ratings obtained from the sample of50 businesstravelers follow.

6,4,5,8,7,6,6,3,3,8,10,4,8,7,8,7,5,9,5,8,4,3,8,5,4,4,4,4,8,4,5,7,2,5,9,9,9,4,8,9,9,4,9,7,8,3,10,8,9,6

Develop a 95% confidence interval estimate of the population mean rating for this airport. (Round your answers to two decimal places.)
