Out of 600 people sampled, 516 had children. Based on this, construct a 90% confidence interval for the true population proportion of people with children. Preliminary: Is it safe to assume that n≤5%n≤5% of all people with children? No Yes Verify nˆp(1−ˆp)≥10.np^(1-p^)≥10. Round your answer to one decimal place.  nˆp(1−ˆp)=np^(1-p^)=  Confidence Interval: What is the 90% confidence interval to estimate the population proportion? Round your answer to three decimal places. _________
