The data in the table were collected from randomly selected flights at airports in three cities and indicate the number of minutes that each plane was behind schedule at its departure. a. Perform a one-way ANOVA using alphaαequals=0.05 to determine if there is a difference in the average lateness of flights from these three airports. b. Perform a multiple comparison test to determine which pairs are different using alphaαequals=0.05 City 1 City 2 City 3 29 48 12 22 24...
