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) Before 68 76 81 75 77 67 72 72 70 78 82 After 70 73 76 68 73 68 70 76 65 75 78 a) State the hypotheses and identify the claim with the correct hypothesis. 1. Ho: PD =0 Not claim H:Hp 0 claim 2. Ho:HD20 Not claim H:Hp <0 claim 3. Ho Ho So Not claim Howo > claim
Ho:Up SO Not claim H:Hp >0 claim b) Find the critical value (s). 01. CV=1.372 O2. CV= 1.812 3. CV= -2.228
