Marjoe breeds German shepherds and trains them to work as service animals for people with disabilities. He is testing the effects of a new training technique on male and female puppies. When a litter is born, he uses the old technique to train them for four weeks and then tests them. For the following four weeks, he trains them using the new technique. He tests them again so that he can compare the scores they attained after the old training to those they attain after the new training. Which test statistic should he use to determine whether the new training is better than the old training?
