Stem-and-Leaf Graphs (Stemplots), Line Graphs, and Bar Graphs: example 2.5

By the end of 2011, a social media site had more than 146 million users in the United States. Table 2.9 shows three age-groups, the number of users in each age-group, and the proportion (percentage) of users in each age-group. Construct a bar graph using this data.

Age-Groups	Number of Site Users	Proportion (%) of Site Users
13–25	65,082,280	45%
26–44	53,300,200	36%
45–64	27,885,100	19%
