The article "Ozzie and Harriet Don't Live Here Anymore" (San Luis Obispo Tribune, February 26,2002 ) looked at the changing makeup of America's suburbs. The article states that in the suburbs of the nation's largest cities, nonfamily households (for example, homes headed by a single professional or an elderly widow) now outnumber married couples with children. The article goes on to state: In the nation's 102 largest metropolitan areas, "nonfamilies" comprised 29 percent of households in 2000 , up from 27 percent in 1990 . While the number of married-with-children homes grew too, the share did not keep pace. It declined from 28 percent to 27 percent. Married couples without children at home live in another 29 percent of suburban households. The remaining 15 percent are single-parent homes. Use the given information on type of household in the year 2000 to construct a frequency distribution and a bar chart. (Make sure to only extract the year 2000 percentages from the given information.)
