An executive believes that a new energy drink his company developed will increase an individual's stamina. In order to test this, he selects random individuals and times how long they can run without stopping. He then instructs the individuals to drink the energy drink for two weeks. After the two weeks, he times how long they can run again without stopping. If we were to perform a hypothesis test on the difference between running time after drinking the energy drink and running time before drinking the energy drink, what would be the null and alternative hypotheses?
