please answer the following questions in the image and make the graph

The table below shows the share of income received by each fifth of income earners, from lowest to highest, in three hypothetical countries. 1 2 3 4 5 (lowest) (highest) Country 1 9 18 25 41 Country 2 4 9 18 24 45 Country 3 12 19 24 36 a. Calculate the cumulative distribution of income among the five groups of income earners in each country. Enter your responses below rounded to a whole number. 2 3 4 5 (lowest) (highest) Country 1 Country 2 Country 3 b. Draw a graph showing the three countries' Lorenz curves. Plot 6 points for each curve, Including the origin point (0, 0), for a total of 18 points plotted below. To manually enter plotting coordinates click on a line segment between 2 points then click on the widget icon to bring up the curve properties box.
