You want to know if the type of music one listens to while running impacts their speed. You recruit 50 participants. These participants listen to classical music while running two laps on a track. You time how long it takes each person to run those two laps. A week later, the same participants run two laps on the track while listening to country music. You time how long it takes each person to run those two laps. All else held constant, which of the following would increase power? O Use alpha .01. O Reduce participants to 40. O Use a directional hypothesis. O Conduct a between-subjects design.
