1) Using the data you obtained for Armenia and Costa Rica, calculate the correlation coefficient (using CORREL command in excel) between openness and GDP per capita (which is a proxy for economic development) for each nation. Report and interpret this relationship and state for which country this relationship is stronger. Correlation - Armenia : 0.102643273 , Costa Rica : -0.873690586

2) Using the data you obtained for Armenia and Costa Rica, calculate the correlation coefficient (using CORREL command in excel) between Openness and the GINI Index (which is a proxy for the ratio of skilled to unskilled wages for each nation in empirical studies).1 Report and interpret this relationship and state for which country this relationship is stronger.

Correlation - Armenia : 0.494817181 , Costa Rica : 0.196984565

3)Assume that both Armenia and Costa Rica are unskilled-labour abundant. First define, Stolper-Samuelson theorem and then check whether your data findings from Step 2 are in line with the Stolper-Samuelson theorem. Explain your answer..
