Obstacle Course Times An obstacle course was set up on a campus, and 8 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 a=0.10 to conclude that the students did better the second time? Assume the variables are normally distributed.
