Statistical poll question

I interviewed 100 people. I asked them to look at a photograph of 2 men. One is 17 years old and the other is 20 years old. The people interviewed had to guess who was the older looking man in the photograph. 76 people chose the man on the right as the older man. What conclusion, if any, can I conclude regarding who is older? For example, tell me something like, “I can only guess that the man on the right is probably older”. Or tell me specifically, using percentage confidence levels. That is, the man at the right is older at a confidence level of 76%. Thanks.

Didn't you already know which was the older man?
You cannot conclude anything from this "experiment."
Where the observers and the photos of the same race?
How different appearing where the two men?
