Please write your name on each page: _______________________________________________ Question 1. Read in the MAU dataset BOStoATL.mtw . This gives information on the average performance of all flights between Boston and Atlanta over 122 days. Focus on the variable in C14: AirDeviation. This is the difference between the actual air time and the planned air time ("ETE" = estimated time en route"). If the airlines are planning well and the deviations are the result of many small random factors, then certain hypotheses should be true. Test each one. In each case, first state whether you retain or reject the hypothesis, then briefly state what statistical technique you used, and finally report the relevant Minitab p-value that justifies your conclusion about the hypothesis. a) [3 points] Hypothesis 1: The distribution of AirDeviation should be normal.
