The World Bank works internationally with the goal of reducing poverty. Their website tracks population by country. The SAS data set called POPULATION contains data on the estimated number of residents (in 100,000s) of various countries by year.

1. Examine this SAS data set including the variable labels and attributes. Make a histogram of the most recent population estimates (Y1) for all countries combined. (Somehow Y1 is the most recent year of population estimates instead of Y4.)
2. Make separate histograms of the most recent population estimates for each continent.
3. Make a single graph with box plots of the most recent population estimates per continent.

I am a little confused and need some help understanding how these steps are done correctly.
