I need help with my HW

Re: I need help with my HW

hhmm it has to do with the Lorenz Curve, I can't figure out how to graph it.. I am not sure what would go on my X and Y axis.

It gives me data of a country for income distribution... Poorest 40 % , Next 30%, Next 20%, Richest 10%
And its for Bolivia- on the bottom it has numbers with each of the percentages I just gave..13, 21,26,40 respectively..

I don't know how to tile it together .... like where to split the percentages, I tried to look at few examples online, but it didn't click on how they graphed it.
