I have a question about the Facebook Groups Administrators?

[Diana]

Can a Facebook Group Administrator(s) see the group's members full profiles even though said members have their Facebook profiles set to private? I am an administrator of a group on Facebook and have only 27 members. I can see most of their profile information when visiting their Time lines to include photos, etc. I would like to reassure my members that I cannot see their personal information if they are set to private, but I have no way of knowing that for sure without asking each member. I really don't want to do that just yet. Thank you!
I have had a member ask this question as she saw on the Net a story that stated Administrators can see its members info on these Facebook groups. That's why I'm asking this question.
