Giovanni,
It is absolutely appropriate. That is the best place to refer them to for answers to those types of questions, precisely because there is no specific answer! Salaries can vary greatly, we all know that is the reality, but we cannot withhold information from our prospective students.
It sounds like you have a supportive team and you can probably already see the importance of admissions and financial aid working closely together to provide the most accurate information possible to the students.
