Six students were unhappy with their final exam grade and areallowed to take a review course during the summer and take anotherfinal. The distribution of all final exam grades is approximatleynormal. We consider these 6 students to be the represetative of allstudents who might take this review course. We have 2 final examscores for each student. Does the data provide sufficient evidencethat the review course improves final exam grades for this course?Use a 1% level of significance. Is this a 2-sample test or a match-pairs test? What are the hypotheses? Is the test statistic a z or a t? The test statistic is -1.75, find the p-value using-1.75 Six students were unhappy with their final exam grade and areallowed to take a review course during the summer and take anotherfinal.

Explanation / Answer

Is this a 2-sample test or a match-pairs test?
match-pairs test

What are the hypotheses?
Ho:D>=0
Ha:D<0

Is the test statistic a z or a t?
t

The test statistic is -1.75, find the p-value using -1.75
p-value is P(t(df=n-1=5)<-1.75)= 0.0702 (checkstudent t table)
