Trying to improve the techniques I use in the classroom and reduce the anxiety of the students, I decided to try an experiment. I decided that I would incorporate more relaxation techniques prior to exams. For a comparison, I subjected the students to twice the exams (evil, I know). In essence, I did a pre- and post-test. The scores are below. At α = 0.05, can it be concluded that the relaxation techniques helped improve test scores?

No relax	85	72	91	56	80	94	82	78	68
Relax	87	70	92	68	79	93	86	72	70

(For each of the problems you must state: the hypotheses and identify the claim, state the test value, p-value, make a decision and summarize the results.)
