Question 1156522: Out of 400 people sampled, 316 had kids. Based on this, construct a 95% confidence interval for the true population proportion of people with kids. Give your answer to three decimal places. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! p hat=316/400=0.79
95% CI half-interval is 1.96*sqrt(0.79*0.21/400)=1.96*0.,0204=0.0399 rounding at end
this would be added and subtracted from 0.790
(0.750, 0.830)
