Instruction:
Using the steps in hypothesis testing, test the following hypotheses using the appropriate test statistic.
A sports researcher would like to determine if the “wonder wristband” can increase the speed of runners. He took the 100m dash time of 6 runners before wearing the bracelet, their time follows: 9.82, 10.12, 7.89, 8.12, 8.59, 8.49 and then the same runners’ time while wearing the bracelet: 9.99, 10.52, 7.50, 6.54, 8.99, 6.87. Find out if there is a significant difference in time without the bracelet and with the bracelet.
