Wilcoxon RankSum Test. In Exercises 58, use the Wilcoxon ranksum test.TaxiOut Times Listed below are samples of taxiout times (min) for American Airlines Flights 19 and 21 (from Data Set 15 in Appendix B). Use thesample data to test the claim that taxiout times for Flight 19 and Flight 21 have the same median. Use a 0.05 significance level.Flight 19 15 12 19 18 21 20 13 15 43 18 17 19Flight 21 13 20 12 17 35 19 22 43 49 45 13 23
