An obstacle course was set up on campus, and 8 randomly selected volunteers were given a chance to complete it while they were being timed. Then they sampled the new energy drink and ran the course again. Is there sufficient evidence to say that the results were any different the second time? Alpha=0.05

Before: 76,89,78,67,56,80,88,67

After: 77,88,65,55,80,85,65

(Note: Testing the difference between two means - dependent samples. )
