Question
In an effort to improve the mathematical skills of 15 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=0.01. 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. pre-test post-test 91 40 66 55 62 79 82 91 78 80 41 47 48 50 60 68 58 68 62 72 49 56 Which of the following are the correct hypotheses?
