In problem 8.16, a college chemistry instructor thinks the use of embedded tutors will improve the success rate in introductory chemistry courses. The instructor carried out a hypothesis test and found that the observed value of the test statistic was 2.33. The p value associated with this test statistic is 0.0099. Explain the meaning of the p-value in this context. Based on this result, should the instructor believe the success rate has improved?

Problem 8.16

A college chemistry instructor thinks the use of embedded tutors will improve the success rate in introductory chemistry courses. The passing rate for introductory chemistry is 62%. During one semester, 200 students were enrolled in introductory chemistry courses with an embedded tutor. Of these 200 students, 140 passed the course.
