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. 71.2% of those
students replied that, yes, they believe that same-sex couples
should have the right to legal marital status. Suppose that you
randomly pick six first-time, full-time freshmen from the survey.
You are interested in the number that believes that same-sex
couples should have the right to legal marital status. What is the
standard deviation (σ)? (Round your answer to four decimal
places.)
