In an effort to improve the mathematical skills of 11 students, a teacher provides a weekly 1-hour tutoring session. A pre-test is given before the sessions and a post-test is given after. The results are shown here. Test the claim that there was an increase in the scores. at a-0.05. You believe that the population is normally distributed, but you do not know the standard deviation. When calculating difference use Post- test minus Pre-test.

O There is not enough evidence to reject the claim that there was an increase in the scores.
