A company researcher wants to test a new formula for a sports drink that has been designed to improve running performance. Instead of the regular "carbohydrate-only" drink that the company produces, this new sports drink contains a "carbohydrate-protein" formula. The researcher would like to know whether this new carbohydrate-protein sports drink leads to a difference in running performance compared to the carbohydrate-only sports drink. To carry out the experiment, the researcher recruited 20 middle distance runners. All of these participants performed two trials in which they had to run as far as possible for 2 hours on a treadmill. In one of the trials, all 20 participants drank from a bottle containing the carbohydrate-only formula. In the other trial, the same 20 participants drank from a bottle containing the carbohydrate-protein formula. Whilst all participants completed both trials, the order in which they underwent the trials differed, which is known as counterbalancing. At the end of the two trials, the distance each participant ran (in km) was recorded. A) Determine whether there is a statistically significant difference in distance run between the two trials (i. e., when using the carbohydrate-protein drink compared to the carbohydrate-only drink). B) What assumptions is necessaray about the population dsitribution in order to perform this test
