Mia has been watching her sister play soccer. She notices that soccer players that wear Adidas cleets, seem to have more accuracy in hitting the goal than players that wear Nike cleets. She thinks it might be because the Adidas have more surface area on the top of the shoe. She designs an experiment to discover if cleets make a difference in a player's ability to score. What is her hypothesis?
What is If a player wears Adidas, then they are more likely to hit the intended target because of the larger surface area of the cleet.
