A sаmple survey is given tо independent rаndоm sаmples оf 500 high school students and 550 college students. Researchers want to estimate the difference in the proportions of high school students and college students who are employed. In all, 20.4% of the high school students and 45.1% of the college students surveyed are employed. Let p1 = the proportion of all high school students who are employed and p2 = the proportion of all college students who are employed. Check if the conditions for calculating a confidence interval for p1 − p2 are met. Calculate a 99% confidence interval for the difference (High school − College) in the proportions of all students who are employed. Based on the interval found above, is there convincing evidence of a difference in the proportions of high school students and college students who are employed? Explain your reasoning.
