A study wished to examine if an intensive coaching session would reduce the mean 100 metre running time for athletes. Athletes were times for 100 metre sprints. The next day, the same athletes were given an intensive coaching session. The following day, the same athletes were timed for another 100 metre sprint. The mean 100 metres running time reduced by 0.26 seconds. Will this hypothesis test be one-tailed or two-tailed? Group of answer choices Two-tailed, because that's how the research questions is framed. One-tailed, because the running time reduced after the coaching. One-tailed, because that's how the research questions is framed. Two-tailed, because the running time changed after the coaching
