Math was chosen by 230 of the 1000 as the favorite subject, and it was also chosen by 362 of the 1000 as the least favorite subject. (a) Construct a 95% confidence interval for the proportion of U.S. adults for whom math was the favorite subject in school. (Give the answers to four decimal places.) ( , ) (b) Construct a 95% confidence interval for the proportion of U.S. adults for whom math was the least favorite subject. (Give the answers to four decimal places.) ( , )
