Suppоse reseаrchers wаnt tо knоw how а new diet affects weight loss compared to a standard diet. Researchers recruited 200 subjects and then grouped the subjects into 100 pairs based on their age and gender. For example: A 25-year-old male will be paired with another 25-year-old male, since they “match” in terms of age and gender. A 30-year-old female will be paired with another 30-year-old female since they also match on age and gender, and so on. Then, within each pair, one subject will randomly be assigned to follow the new diet for 30 days and the other subject will be assigned to follow the standard diet for 30 days. At the end of the 30 days, researchers will measure the total weight loss for each subject. The data is shown below. For the purposes of running this matched pairs t-test, what are the correct number of degrees of freedom?
