Strengthening Argument on Tuition Increase Impact

A local university's recent survey reported that 90% of its students are satisfied with the quality of education provided.

Despite this high satisfaction rate, the university has faced declining enrollment figures over the past two years.

University officials argue that the low enrollment is due to an increase in tuition fees rather than the quality of education. To support this argument, they reference a previous study indicating that when tuition increases occur, student enrollment tends to decrease.

Which of the following statements, if true, would most strengthen the university's argument that the tuition increase, and not educational quality, is the primary cause of declining enrollment?
