# Alex thinks that at the U of I, male students tend to eat out more often than female students

Question posted by

Alex thinks that at the U of I, male students tend to eat out more often than female students. To test this hypothesis, he randomly selects a group of 31 male students and a group of 35 female students who have access to a kitchen (living off-campus or in an apartment on-campus). He asks each of them if they eat out more than 5 meals per week. Of the 31 male students, 12 said yes. Of the 35 female students, 23 said yes.

Find the 97% confidence-interval for the true difference in the population proportions of male and female students at the U of I who eat out more than 5 meals per week (male - female).
