Two random samples were drawn from members of the U.S. Congress. One sample was taken from members who are Democrats and the other from members who are Republicans. For each sample, the number of dollars spent on federal projects in each congressperson's home district was recorded.Dollars Spent on Federal Projectsin Home DistrictsLess than S to 10 More than5 Billion Billion 10 billionPartyRow TotalDemocratic T 10 T 12 23 TRepublican4512171847Column Total22294192(1) Make a cluster bar graph showing the percentages of Congress members from each party who spent each designated amount in their respective home districts.
