A random sample ofaircraft times gives the following results in minutes: 10.1, 19.3, 24.3, 3.1, 20.3, 20.7, 14, 14.2, 14.1, 12.1, 14.6, 11.4, 12.8, 18, 23.5, 16.9, 14.4, 12, 12.4, 32.6, 18.4, 14.6, 14.9, 20.4, 13.3, 8.6, 21.2, 11.3, 17.5, 11.8, 24.4, 14.7, 13.2, 14.5, 7.5, 10.4, 4.1, 9.3 Again, each value represents the number of minutes that an aircraft spent crossing the airspace of that airport. 1. Produce a 90%, 95%, and 99% confidence interval for this sample. You may, of course, use R for your calculations. 2. Thought question: There is a substantial variation to this data set. Why do you think that is
