Good job. I see that you have the skill of producing scatter plots and weighted averages. Close to approval, not yet.

    I do not understand the logic between air pollution death and sanitation though. Sanitation is directly related to water infection diseases, but I am not sure about its relation to air pollution death. Am I missing something? Can you elaborate more on this?

    For weighted averages, you should report both weighted average fors death measure (weighted by total population) and sanitation measure (weighted by total population). It seems that you are using the death rate as a weight for sanitation measures, which is weird. Give me an update when you improve on these. Also remember to give me “edit access.” I think only get “view” access now.
