A comparison is made between two bus lines to determine ifarrival times of their regular buses from Denver to Durango are offschedule by the same amount of time. For 51 randomly selected runsbus line A was observed to be off schedule by an average time of 53minutes with a standard deviation of 19 minutes. For 60 randomlyselected runs bus line B was observed to be off schedule anaverage of 62 minutes with a standard deviation of 15 minutes. Dothe data indicate a significant difference in average off scheduletimes? Use a 5% level of significance. a.Level of significancenull and alternative hypothesis b.
