workers, aged 18 and older, living in all 50 U.S. states and the District of Columbia, revealed that 52% of salary workers are "satisfied" with their
relations with coworkers. From these results, the 95% confidence interval for the population proportion of all salaried workers in the US who are
"satisfied" with relations with their coworkers is given by (0.4872, 0.5528).
