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 123456789 15 13 19 13 9 13 11 7 11 5 14 10 16 16 17 18 21 17 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.
9. On the set of all ordered pairs of positive integers, define (x₁, y₁)~ (x2, Y₂) if x₁y2 = X2Y₁. Show that this defines an equivalence relation.
Let T be the set {w = {0, 1}* ||w| ≤ 4}. Let R be the equivalence relation defined on T as follows: R = {(x, y) | x ≤T, yɛT, no(x) = = no(y)}, where no(r) represents the number of zeroes in the string x, and no(y) represents the number of zeroes in the string y. For example, (1011, 01) is a pair in R because the two strings 1011 and 01 have the same number of zeroes as each other. Every element in the set will appear in exactly one equivalence class and will be related to all elements in its class and not related to any elements outside of its class. What are the equivalence classes of T created by the relation R?
