3. For this problem, use the SAS Studio dataset SASHELP.DEMOGRAPHICS. Data in this dataset includes population values for 900+ countries and 6 regions based on the Global Burden of Disease (GBD) regional classification system. The 6 regions in the database are the African Region (AFR), Region of the Americas (AMR), Eastern Mediterranean Region (EMR), European Region (EUR), South-East Asian Region (SEAR), and Western Pacific Region (WPR). The variables needed for this assignment are REGION and POP (Population in 2005). Test the hypothesis that at least one of the regions has a significantly different population count than the others. Answer the following questions: a. Assuming the data is normally distributed and randomly selected, what is the null hypothesis (in words, in terms of the problem)? b. What is the alternate hypothesis (in words, in terms of the problem)? c. What is the p-value for the hypothesis test? d. What is the decision? Justify your answer. e. What is the conclusion in terms of the problem? f. If the results of the test are significant, perform the appropriate test and explain which regions have significantly different populations
