A sample of 20 countries has been randomly selected. Attached is a chart indicating the literacy rate, population, and GDP for each country. Compute the correlation among the variables. In other words, find the correlation between: literacy and population, literacy and GDP, and population and GDP. At the .05 significance level, can we conclude that the correlation is different from zero for each pair of the variables?

Please use Excel and Word as necessary, thanks.
