The 114th Congress of the United States of America has 535 members, of which 108 are women. An alien lands near the U.S. Capitol and treats members of Congress as a random sample of the human race. He reports to his superiors that a 95% confidence interval for the proportion of the human race that is female has a lower bound of 0.168 and an upper bound of 0.236. What is wrong with the alien’s approach to estimating the proportion of the human race that is female?
