A reseаrcher is interested in studying whether оr nоt listening tо music while jogging mаkes people run fаster.  He thinks that listening to music will make people run faster.  Luckily, he knows that, for the population he interested in (runners in Washington, DC), the mean running speed (m) is 6mph, and the standard error is 2mph.  He collects data from a sample of runners that only listen to music, and finds they have a mean running speed (M) of 9mph.   The researcher would like to conduct a One-Sample Z-test.  Please calculate the Z-statistic (Z-obtained)
