To determine whether traffic levels differ between the morning and evening rush hours, a traffic engineer counted the number of cars passing through a certain intersection during five-minute periods in both morning and evening for ten days. The results were as follows. 1 3 44 4 6 7 10 Morning 65 Evening 70 68 64 63 38 36 55 78 47 51 59 49 63 50 59 83 81 25 Can you conclude that the median traffic levels differ between morning and evening? Use the a =0.01 level of significance.
