4. Plane capacity histogram. Create a table that is, essentially, a histogram of the percentages of how full planes have been on the flights that they have made (that is, only the flights that have actually departed). The capacity of a plane includes the seats from all of its seat classes. The upper bounds in the ranges below are non-inclusive. Attribute airline the airline of the plane. tail number the tail number of the plane. very_low The number of flights that the plane had between 0% and 20% capacity. low The number of flights that the plane had between 20% and 40% capacity. fair The number of flights that the plane had between 40% and 60% capacity. normal The number of flights that the plane had between 60% and 80% capacity. high The number of flights that the plane had more than 80% capacity. Everyone? Every plane should be included, even if they haven't flown at all. Duplicates? No plane can be included more than once.
