### Problem 3 It is hypothesized that humans originated in East Africa, and migrated from there. A measure of genetic diversity for different populations (Ramachandran S., Deshpande O., Roseman C.C., Rosenberg N.A., Feldman M.W., Cavalli-Sforza L.L., " Support from the relationship of genetic and geographic distance in human populations for a serial founder effect originating in Africa," Proceedings of the National Academy of Sciences, 2005, 102 15942 - 15947)and the geographic distance of each population from East Africa (Addis Ababa, Ethiopia), as one would travel over the surface of the earth by land (migration long ago is thought to have happened by land) were computed. The relationship between these two variables is included in the dataset $GeneticDiversity$.

a) Import the dataset $GeneticDiversity$ from the textbook website and do a preliminary analysis of the content of it. Additionally, identify which variables might be considered categorical and which ones nnumerical or quantitative?

b) Make a scattered plot including genetic diversity and distance from East Africa as variables. Add to the plot the linear model. Does there appear to be an association? If so, it is positive or negative? Strong or weak? Linear or nonlinear?
