A researcher wants to study the effects of a high school
student's college campus visit on the likelihood of enrolling the
following year for under- privileged students who are not likely
to attend college. 250 students were selected to participate in a
study, where the costs of a campus visit were
completely paid
for. Of those, 225 agreed to participate. Seventy-five students
were
randomly assigned to visit college 1, 75 were assigned to visit
college 2, and 75 were assigned to visit college 3. In the fall, the
enrollment of each student was checked to determine effects of
the visit.
