To raise revenues, many airlines now charge fees to check luggage. Suppose that the number of checked bags was recorded for each person in a random sample of 100 airline passengers selected before fees were imposed and also for each person in a random sample of 100 airline passengers selected after fees were imposed, resulting in the accompanying data. Do the data provide convincing evidence that the proportions in each of the number of checked bags categories is not the same before and after fees were imposed? Test the appropriate hypotheses using a significance level of .05.
