An obstacle course was set up on a campus, and 10 volunteers were given a chance to complete it while they were being timed. They then sampled a new energy drink and were given the opportunity to run the course again. The “before” and “after” times in seconds are shown below. Is there sufficient evidence at α = 0.05 to conclude that the students did better the second time? Discuss possible reasons for your results.
a. State the hypotheses and identify the claim.
