A random sample of elementary school children in New York state is to be selected to estimate the proportion p who have received a medical examination during the past year. The survey found that x = 468 children were examined during the past year. Construct the 95% confidence interval estimate of the population proportion p if the sample size was n = 600. Give your confidence interval bounds to at least 4 decimal places. __________ < p < _________.

Question

(a) A random sample of elementary school children in New York state is to be selected to estimate the proportion p who have received a medical examination during the past year. The survey found that x = 468 children were examined during the past year. Construct the 95% confidence interval estimate of the population proportion p if the sample size was n = 600. Give your confidence interval bounds to at least 4 decimal places.

__________ < p < _________.

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
