After consulting with the universitys statistics department, it was decided that over the next month the following study would be conducted. Ten cities with at least 100 applicants would be selected for inclusion in the study. To each of these cities 100 standard packages would be sent by each of the four methods of delivery. The percentage of packages not delivered within 5 days was recorded for each method of delivery, yielding the following data. For four of the cities, at least one of the methods of delivery did not provide service, and, hence, there are missing data in these cells.
