Final answer:
The claim about Hispanics having the lowest high school completion rate in 2009 is false. Data from the US Census Bureau shows improvements in Hispanic educational attainment, and by 2013, their college enrollment rates even surpassed whites.
Step-by-step explanation:
The statement that Hispanics aged 18 to 24 had the lowest rate of high school completion compared to whites and African Americans in 2009 is false. The Educational Attainment data from the United States Census Bureau for 2014 indicates that there were significant improvements in education attainment among Hispanics after the 1980s, where dropout rates were initially higher.
By 2014, the high school completion rate among Hispanics had increased, counteracting the trend seen in previous decades. Furthermore, according to Pew Research Center in 2013 Hispanic college enrollment rates surpassed those of whites, indicating positive progress in educational achievements.
