Question 2 (1 point) To test the effectiveness of a business school preparation course, 6 students took a general business test before and after the course. The results are given below. Student 2 3 4 5 6 Score before the course 520 600 900 830 610 550 Score after the course 650 600 1000 970 710 810 Is there evidence that the means test scores are different before and after the business school preparation course? Test the appropriate hypotheses at the 0.10 level of significance. Denote by Up the mean of the differences of the scores before and after the course for all students, where D="Score Before - Score After". Denote by M1 and M2 the means of scores before and after the course for all students, respectively. Find the standardized test statistic and p-value. Round to 4 decimal places. Otest statistic= -2.9800 p-value=0.0029 O test statistic= -2.5277 p-value=0.0464 Otest statistic=-3.5477 p-value=0.0082 test statistic= -3.5477 p-value=0.0164 ONone of the other answers are correct
