A career Web site for college students and alumni surveyed 200 recent graduates and found that 63% had accepted a job in a new city, state, or country. The approximate standard deviation for the distribution of sample proportion in this case is 0.034.

(a) What is an approximate 95% confidence interval for the population proportion who accepted a job in a new city, state, or country? (Round your answers to two decimal places.)

(b) What should be checked before we use the interval to estimate the proportion of all recent U.S. college graduates who accept a job in a new city, state, or country?
