Despite tuition skyrocketing, a college education is still valuable. Recent calculations by the Federal Reserve Bank in San Francisco demonstrate a college degree is worth $800,000 in lifetime earnings compared to the average high school education. If graduates earn $37,632, $35,794, $43,392, $34,752, $70,591 and $48,368. What is the standard deviation for this sample? Note: Round your intermediate calculations and final answer to the nearest whole number. Answer is complete but not entirely correct. Standard deviation $ 12,335
