The population of the United States is aging, though less rapidly than in other developed countries. Above is a stemplot of the percents of residents aged 65 and older in each of the 50 states, according to the 2000 census. There are two outliers: Alaska has the lowest percent of older residents, and Florida has the highest. What is the percent for Florida?
