Two airlines on the same route cost the same, so you decide to compare them by their On-time Rating. You take a sample of 30 flights from each airline and compare the number of minutes they arrived before, or after their scheduled arrival times. Flights are dened as being on time ifthey arrive no later than 5 minutes after their scheduled arrival time. Negative numbers represent the minutes a flight arrived before its scheduled time. Positive numbers represent the minutes a ight arrived after its scheduled time. Zero indicates a ight arrived at its scheduled time. Airline P: 'On-time Rating' (minutes) -25, 0, 25, -15, 5, -20, 5, 15, -10, D, -15, 10, 15, -5, -5, -10, 15, 5, D, -S, D, 5, 0, 20, -5, 25, -S, -10, 10, 10 Airline Q: 'On-time Rating' (minutes) -35, 0, 30, 5, -1D, -5, 0, 45, 5, -25, -20, 10, 60, -5, 0, D, -10, 30, 15, -15, -10, 20, 20, -15, 0, D, -5, 25, 10, -25 a) Complete a Numerical Summary, using Excel, for each Airline for the sample statistics outlined below [The data is entered in the '247005 A1 2202' spread sheet] b) Using Excel, construct Box Plots to compare the performance of Airlines P and (1.
