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.

Hint: Refer to sections 8.3 and 8.4 as you work through this assignment.

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.
4. In a comment in your program, describe the main differences between the statistical information that can be visualized in the histograms from part b) compared to the box plots from part c).
5. make a header comment at the top of your program with your name, the date, the assignment name (GPA8), and the filename (YourLastName.GPA8.sas)
6. make a libref for your data sets at the top of your program after the header comment so I can edit the path and still run your code.

I am a little stuck on these steps and need some help understanding what to do for each one.
