b) find the average vertical leap of all the athletes in their regular shoes. give the experimental group the new shoes and the control group a different pair of shoes. find the average vertical leap of the athletes in both groups. compare the increases in vertical leap for each group.
c) find the average vertical leap of a group of athletes in their regular shoes. then give them each the new shoes and find their average vertical leap. compare the before and after results.
