May I please get help on how to answer this question.

Students in a chemistry class took a short test, then completed an online tutorial, then re-took the test. The points each student received on the test before and after completing the tutorial are given below. At the a = 0.05 level of significance, can it be concluded that completing the online tutorial resulted in improved test scores? Let jug be the mean test score before completing the tutorial, /, be the mean test score after completing the tutorial, and fid = HA - Up. Assume that the test score differences have a normal distribution. (Round your results to three decimal places) Which would be correct hypotheses for this test? O Ho: Ha > 0, H:pa 0 O Ho:14a # 0, H,:pa = 0 O Ho:pa = 0, Hpa 40 O Hotpa = 0, Ha
