A particular poll tracks daily the percentage of Americans who approve or disapprove of the performance by President 1. Daily results are based on random telephone interviews with approximately 1000 national adults. The poll reports that 58% of adults approve of President 1. The same poll reported an approval rating of 59% for President 2. A news anchor remarks that "President 1 doesn't even get as much approval as President 2 did." Is there evidence that this difference is real? State and test the appropriate hypotheses. Check conditions.
