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 405 children were examined during the past year. Construct the 95% confidence interval estimate of the population proportion p if the sample size was n = 500. Give your confidence interval bounds to at least 4 decimal places. < p < (b) Which of the following is the correct interpretation for your answer in part (a)? A. We can be 95% confident that the percentage of all elementary school children in NY who have received medical examination during the past year lies in the interval B. We can be 95% confident that the percentage of elementary school children in the sample who have received medical examination during the last year lies in the interval C. There is a 95% chance that the percentage of all elementary school children in NY who have received medical examination during the past year lies in the interval D. None of the above
