Acurriculum coordinator wants to know if students tend to score differently on the first and second exams in an introductory stats course. data were collected from a representative sample of 45 students enrolled in the course. data were paired by student. the mean difference, computed as exam 1 – exam 2, was 1.5076 points with a standard deviation of 5.8854 points.

a. use minitab express to conduct a paired means t-test to determine if there is evidence that scores on the two exams are different in the population of all students in the introductory stats course. use the five-step hypothesis testing procedure given below. remember to include all relevant minitab express output and to clearly identify your test statistic and p value. do not do any hand calculations. [25 points]

step 1: check assumptions and write hypotheses

step 2: calculate the test statistic

step 3: determine the p value

step 4: decide to reject or fail to reject the null

step 5: state a "real world" conclusion
