The airline industry defines "no-shows" as passengers who have purchased a ticket but fail to arrive at the gate on time for departure. United Airlines operates many flights from Philadelphia to Dallas. The table below represents the observed number of no-shows that occurred on a random sample of 200 flights between Philadelphia and Dallas this year, and experienced the no-show proportions last year. No-shows Observed Proportion 0 5 0.05 1 35 0.15 2 40 0.30 3 120 0.50 Test if the proportions of no-shows has changed between last year and this year on flights between these two cities using a = 0.05. Statistical Value = Critical Value = So, we Ho. (Just type "reject" or "fail to reject") >
