QUESTION 1

A nursing researcher wants to determine if a 1 hour education session with a certified diabetic education will increase the self confidence level regarding self-management of diabetes in a newly diagnosed diabetic patient. The nursing researcher randomly selects 10 newly diagnosed diabetic patients and administers a test designed to measure confidence in diabetic self-care, with “1” being not at all confident and “10” being very confident, before and after the patient’s education session. She obtains the scores below. To test the null hypothesis that diabetes self-care does not improve after attending diabetes education (using a 0.05 confidence level), she conducts a related groups t-test. What are the degrees of freedom for the test?
