A school district wants to know whether a new text-message reminder system changes the proportion of parents who attend parent-teacher conferences. Two similar middle schools are chosen: one uses reminders (n = 180 parents invited) and the other does not (n = 200 parents invited). Attendance is recorded as Yes/No, and the counts are 108 Yes in the reminder school and 90 Yes in the no-reminder school. Which inference procedure is most appropriate to determine whether the reminder system is associated with a different attendance rate?
