- An educator has invented a new way to teach geometry to high school students. To test this new teaching method, the educator matches 16 tenth-graders into 8 pairs based on their grades in previous math courses. Then the students in each pair are randomly assigned to either the new method or the traditional method. At the end of a full semester of geometry training, all students take same standard high school geometry test. The scores for each student in this hypothetical experiment are as follows:

Perform a paired-samples t-test for this experiment (p = .01 or 99% confidence, two-tailed). Is there a significant difference between the two teaching methods?
