Suppose sample of 10 students were given a Mathematics Diagnostic Ass the Math Centre self-learning modules, and then again after completing all the modules from the Math Contre. With the help of the before and after MDA scores, We want to find out if, in general, the Math Centre leads to improvements in de b (MDA) hebre dry we gives to Before and After Test ScoreS Student Before Test Score After Test Score d-Before After 1 42 42 2 63 61 86 91 25 30 49 53 55 60 30 34 71 71 9 77 80 10 35 31 -5 Using the 2.5 % significance level, can you conclude that Math Centre resources helped the students to improve the mean MDA score (Before Score <After Score)?

Which of the following is the correct critical value of 1 for testing the hypothesis from part (a)? Consider a=025, and use the appropriate Table from Appendix C. O-2.262 2.685 2.685 O 2.262

To save computational time, use the following Ed 20 and Ed-136. e. Considering the critical value in part (c) and test statistic value in part (d), we cannot reject the mill hypothesis from part (a) at a= .025 level of significance. O True O False f. We cannot conclude that the mean MDA scores increased as a result of Math Centre resources. True O False Back Submit Assignment Question Menu-
