Problem 3BSC

What Are We Testing? Refer to the sample data in Exercise. Assuming that we use the Wilcoxon rank-sum test with those data, identify the null hypothesis and all possible alternative hypotheses.

Exercise

Flight 19 -5 -32 -13 -9 -19 49 -30 -23 14 -21 -32 11

Flight 21 -23 28 103 -19 -5 -46 13 -3 13 106 -34 -24

Solution 3BSC

For the given problem null hypothesis and the possible alternative hypotheses are

H0: The median of the departure times of flight 19 is equal to the median of the departure time of flight 21.

Possible Alternative hypotheses.

(i) H1:The median of the late departure times of flight 19 is not equal...
