. Problem 5 Consider the following hypothesis for a Wilcoxon signed rank test. Ho : m = 6 versus Hi : m / 6 where m is the mean of the underlying population. a) Determine the p-value of the Wilcoxon signed rank test using the data: F1 = 15, 12 = 7, 23 - 3, 14 - 10, as = 13. Show all your calculations clearly. b) Use the Wilcoxon test in R to generate the p-value and compare with the result obtained in part (a).Consider the following hypothesis for a Wilcoxon signed rank test. Ho : m = 6 versus H, : m # 6 where m is the mean of the underlying population. a) Determine the p-value of the Wilcoxon signed rank test using the data: X1 = 15, 12 = 7, 13 = 3, 4 = 10, x5 = 13. Show all your calculations clearly. b) Use the Wilcoxon test in R to generate the p-value and compare with the result obtained in part (a).A B C D E 1 Research Method | Characteristic 1 Characteristic 2 Strength Limitation 2 Lab Experiment Quasi Experiment Field Experiment 5 Natural Experiment 6 Correlational Study 7 Longitudinal Study 8 Observation 9 Case Study 10 Interview1. Which requirements are necessary for an IV regression? (a) The instrument is independent of the structural error (b) The first stage is strong (c) There are at least as many instruments as endogenous variables (d) All of the above 2. 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 eventPeople might behave very differently in artificial laboratory conditions than they would outside and so their behavior might be very artificial.
