A random sample of workers is selected in a city. Their commute time an minutes) from home to work and from work to home are recorded and shown below.

Part A State the null and alternative hypotheses. Let Md be the median difference in the commute time between from home to work and from work to home for all workers in this city. Note: The difference in the commute time is defined as [From home to work] [From work to home]. HoZMd = V 0 Husz
