0 / 1 pts Which arrangment below correctly orders the procedures from most powerful to least? Wilcoxon Sign Rank test, Chi-Squared test for independence, One Proportion Z-test Kruskal-Wallis, Friedman Fr-test. ANOVA CRD Wilcoxon Rank Sum, Wilcoxon Sign Rank test, Independent t-test The independent Sample Z-test, The independent sample t-test, The Wilcoxon Rank SumQUESTION 6 Two graphical displays are given for a set of data. A hypothesis test is to be performed for the mean of the population from which the data were obtained. Use the graphs to determine whether a z-test, a t-test, a Wilcoxon signed-rank test, or none of these is appropriate.

Scenarios arising which allow diffierence in difference or instrumental variable regression are often referred to as natural experiments. Which of the following is true of a natural experiment? (a) A natural experiment occurs when some endougenous event charges the environment in which individuals, families, firms and cities operate (b) The control group in a natural experiment is randomly chosen (c) The treatment group in a natural experiment is randomly chosen (d) Control and treatment groups in a natural experiment arise due to an exogenous event
