The Research and Innovative Technology Administration of the Bureau of Transportation Statistics reports load factors​ (passenger-miles as a percentage of available​ seat-miles) for commercial airlines for every month from October 2002 through 2017. The accompanying boxplots summarize the data for international flights. Look at the accompanying boxplots by month. The low outlier in April is for April of 2003. At that​ time, there was concern over the deadly SARS​ virus, which may have depressed international travel. Do you think the data for April 2003 should be set aside in overall analysis of load​ factors? Explain.
