Using R Studio pick an airport (not IND) and year of your choice in the data set airlines. You should be using the function subset () to pick year and airport. Next, add a column called delay, which is the share of delays from all the arriving flights. Next, construct a boxplot with all the airlines on the x-axis, i.e., one boxplot, and the variable delay on the vertical axis. Interpret the boxplot. Are there airlines, which are particularly on time or always late?
