[Total 40 points) Answer uestion E1. Power is the ability to reject the null hypothesis when it should be rejected 2. With curvilinear data, the Pearson r statistic is an appropriate, accurate statistical tool In a research report, the term statistically significant is used to indicate that the null hypothesis was rejected 4. If you were to calculate a correlation coefficient of r 2.99, the best thing to do is to reject the null hypothesis and conelude that there is a significant relationship between the variables F The chi square is a statistics used with ordinal data. 6. For the chi square statistics, we reject the null hypothesis if the observed value exceeds the critical value 7. In an independent means t test, the N's for each group do not have to be equal 8. Suppose that it was observed that there is a correlation of r 0.81 between a driver's age F and the cost of car insurance. This correlation means that, in general, older people pay more or car insurance F 9. The values for r can range from -2 to +2, inclusive 10. With r values greater than ,90 or less than-90, the null hypothesis is rejected and cause and effect conclusions are possible 11. The best use of correlational techniques is to demonstrate cause and effect relationships between variables 12. If the null hypothesis is rejected when a ,01, the null hypothesis would also be rejected if 05 F 13, In most research situations, the goal is to reject the null hypothesis F 14. When participants are classified into categories, correlation is the best statistical choice F 15. A t-test involves all interval/ratio data 16. For a one way ANOVA, we reject the null hypothesis if the observed value is smaller than the critical value. F 17. When participants are classified in categories, correlation is the best statistical choice 18. A 95% confidence interval encompasses more values than a 99% confidence interval 19. A Type II error occurs when a treatment actually does have an effect on the scores but the effect fails to show up in a research study F 20. If a research reports that t (6) 3.98, p0.05, then H, was rejected SECTION II. CHI sQUARE. For the chi square problem, be sure to completely fill in the answer box.
