Provide numeric statistical support for the answers to the following questions.
Do not simply write down any and all statistics you have ever learned. Answer the questions and then cite the specific statistic, statistics, or charts that support that answer. When citing a statistic or statistics, include both the name of the statistic and the numeric value. If citing a chart, make a sketch of that chart to support your answer.
