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.
