A researcher examined the effects of mindfulness meditation on stress reduction. The researcher recruited n=9 participants from a university campus and asked them to participate in a 30-minute mindfulness med- itation session every day for two weeks. Before and after the two-week intervention period, the participants completed the Perceived Stress Scale, a standardized self-report measure of stress levels. The participants' stress scores are shown in this table. participant before meditation after meditation 1 15 13 2 19 3 9 4 11 5 11 6 14 10 7 16 16 8 17 18 9 21 17 33752687 13 13 On average, by how much did the anxiety scores change from before versus after the two weeks of meditation sessions? Use a related-samples t-test to determine if this change is statistically significant, and calculate the coefficient of determination r². Report your findings as a sentence or two that could be in the Results section of an APA-style research article.
