The Higher Education Research Institute at UCLA collected data from 203,967 incoming first-time, full-time freshmen from 270 four-year colleges and universities in the U.S. 71.4% of those students replied that, yes, they believe that same-sex couples should have the right to legal marital status.

What is the standard deviation ()? (Round your answer to four decimal places.)
