A professor at UCI wants to see what students really remember from their elementary school days, the stuff that was taught or the stuff that was popular at the time. She put together two tests, one with elementary school education questions and one about pop culture from that time. She got a sample of 9 students and had them take both tests. What test does she use? 1. t-test for the difference between means tor two independent samples with heterogeneity of variance.
2. simple regression.
3. t-test for the difference between means for two related samples.
4. a one sample z-test for proportions for a chi-square goodness of fit).
5. one sample z-test.
6. a two-sample z-test for the difference between proportions for a chi-square test of independence).
7. multiple regression.
8. one-sample t-test.
9. ANOVA
10. Mann-Whitney.
11. chi-square goodness of fit only where a one samplez-test of proportions isn't appropriate).
12. chi-square test of independence only (where a two-sample z test for the difference between proportions isn't appropriate).
13. t-test for the difference between means for two independent samples with homogeneity of variance.
14. Wilcoxon.
