Question
An obstacle course was set up on a campus , and 11 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 = 0.05 to conclude that the students did better the second time?
Assume the variables are normally distributed. (Consider the difference D= Before - After)
