Question

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 ratings obtained from the sample of 50 business travelers follow.

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