survey of 1000 students concluded that 274 students chose a professional baseball team, A, as his or her favorite team. In 1991, the same survey was conducted involving 760 students. It concluded that 240 of them also chose team A as their favorite. Compute a 95% confidence interval for the difference between the proportion of students favoring team A between the two surveys. Is there a significant difference?
