Match the study with the best hypothesis test that could be used to evaluate the research question.Do exercise supplements improve the effect of training among amateur runners? 112 amateur runners were enrolled in a study in which they ran using a proven 12-week 5km race training plan. At the beginning of the 12-week study, they ran a 5km race, their finishing times were recording; they repeated the same race at the end of the 12-week study. Half of the enrolled participants were instructed to consume a daily exercise supplement that was provided to them, the other half were not. The researchers wanted to know if there would be a difference in the 5km race time at the end of the study for two runners who had the same 5km race time at the beginning of the study, if one was given the exercise supplement and the other was not.
