For the time being, the air traffic control system in the United States is run by the federal government. Several groups disagree with thisand would like to privatize the air traffic control system. Among the arguments given for privatization is that flight delays are much toocommon in the United States. A first step in deciding if, indeed, delays in the U.S. are "too common" might be to compare the flightdelay information from the U.S. and other nations.You have in front of you the following chart, which summarizes the information from three samples of flights from the past six weeks.One of the samples is composed of domestic U.S. flights, one is composed of domestic Canadian flights, and one is composed ofdomestic British flights. The information recorded for each flight is the time (in minutes) that the plane was late to the arrival gate. (Ifthe plane was early, the time recorded was negative.)Sample SampleSamplevarianceGroupssizemeanUnited States21018.597.3Canada23419.397.1Great Britain22616.695.0Send data to calculatorYou perform a one-way, independent-samples ANOVA test to decide if there are differences in the mean flight delay times among thethree countries.
