The International 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 the Miami International Airport. The file Miami contains the ratings obtained from the sample of 50 business travelers. Develop a 95% confidence interval estimate of the population mean rating for Miami. Round your answers to two decimal places. DATA file 6 4 6 8 7 7 6 3 3 8 10 4 8 7 8 7 5 9 5 8 4 3 8 5 5 4 4 8 4 5 6 2 5 9 9 8 8 9 9 5 9 7 8 3 10 8 9 6
