The Gallup organization conducted a phone survey in October 2020. Researchers at Gallup chose a random sample of 1020 US registered adult voters, aged 18 or older who lived in the continental U.S. The random sample was selected by a computer; 400 men and 620 women were selected in the sample. The 1020 American adults were asked to respond to the following Yes or No question: "Are you confident that mail-in ballots are being counted correctly in elections." Gallup wishes to determine if the percentage of women who answer "Yes" to the question is higher than the percentage of men who answer "Yes" to the question. Assume all checks have been verified
