Question 1187180: Out of 300 people sampled, 195had kids. Based on this, construct a 95% confidence interval for the true population proportion of people with kids Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! p=195/300=0.65
95% half-interval for a proportion is z(0.975)*sqrt(p(1-p)/n)
so this is 1.96*sqrt(0.65*0.35/300)
=0.054
the interval is (0.596, 0.704)
