All Harrison University Students live in either Pulham or Westerville.

A small fraction of the classes at Harrison are night classes.

38% of Harrison students take at least one night class.

29% of students living in Westerville take at least one night class.

If a student doesn’t live in Westerville, the student lives in Pulham.

Over 38% of students living in Pulham take at least one night class.

Must be true. Since all students live in either Pulham or Westerville, the overall 38% night-class enrollment is an average of both groups. Westerville students have a lower rate (29%), meaning Pulham students must have a higher rate to balance the overall percentage at 38%.

Could be false. We don’t know how many students live in each dorm. It could be the case that Westerville has more students than Pulham––in this case, over 50% of the night class students would be from Westerville, even though only 29% of Westerville students take night classes.

Could be false. We don’t know anything about the relative sizes of the two residence complexes.

Could be false. We don’t know anything about people who take more than one night class. The stimulus only discusses students who take at least one night class.

Could be false. We don’t know anything about the enrollment size of day classes.
