Using VB Excel, you will create two new columns- Average Delay and Efficiency. Average Delay is the average of the arrival delay and departure delay, and efficiency column will classify each row as efficient or inefficient. If a flight has more than 14 minutes of “average delay” then classify it as inefficient or else efficient. A command button (named Add Columns) should be used to populate the values of these two columns.
