A sports equipment manufacturer has developed a new reasonably priced golf ball that it hopes will allow average golfers to hit the ball straighter. A concern is that this new technology might impact on the distance that the ball travels. To compare distances, Sarah, a company researcher, conducts an experiment where 20 current balls and 20 new balls are subjected to distance tests, using a mechanical hitting device for consistency. The results of the tests, with distances given to the nearest metre, are given in Table 1.
