Question: For years, the proportion of passengers with more than one piece of carry-on luggage has been stable at approximately 38%. A commercial airline is concerned that this proportion has changed recently. They randomly selected 200 passengers and determined that 82 possessed more than one piece of carry-on luggage. Do they have evidence at α = 0.05 that the proportion with more than one carry-on has changed?
