1. What should be the total sample size "n" representing all groups (round-off:integer) if we expect to see a large effect size (Cohen's f-0.04) in a repeated measures ANOVA, given the # of countries (k) represented by our West Asia total count data (2008-2012), with sig. level=0.05, and power=0.8?

2. What would be the appropriate statistic to check normal distribution for the test of differences and potential interactions for migration counts with "region" and "status" as the two factors? Write the acronym from these options: SW (Shapiro-Wilk), JB (Jarque-Bera), AD (Anderson-Darling)

3. What would be the minimum total samples size needed for the current data set, when considering "years" as factor A, "region" as factor B, alpha sig.=0.05, beta sig.=0.1, with Cohen's f=0.4 for both factors, with "1" as the smallest difference in both factors, and with both year and regions having an estimate max. SD = 29000.
