1. Your research study is investigating whether the use of a new medication will have an effect on fatigue levels (as measured by a Likert scale, where 1 is no fatigue and 10 is extreme fatigue) in patients with a diagnosis of Chronic Fatigue Syndrome. The fatigue level is measured at the beginning of the study and again at the end of a 10-week study. Use a 95% confidence level.

a) What is the best statistical test to run (2 points):

b) Run the test in SPSS and paste the important tables below (2 points):

c) What are the median scores for pre- and post-study fatigue? (2 points)

d) What is the Z score? (1 point)

e) What is the p value? (1 point)

f) Is there a statistically significant difference between the groups (did the medication work)? (2 points)
