A university wants to know if a four-week mindfulness training program reduces student stress levels. Students complete a standardized stress questionnaire (multiple item rating scale) one week before the program begins and again immediately after the program ends. The goal of the study is to determine whether stress levels change after participation in the mindfulness program. Conduct the appropriate statistical test to determine whether there is a significant change in stress levels from before to after the program.
