Don't think so, not specific enough, I think. Although I'm always curious why people ask such a question. How does knowing this help? You ask 100 people and they will give you 100 different answers, because no one has the same site, same niche, same layout, same design, same visitor traffic, etc. I.e. "It varies."
I think you'll get a better idea if you started a poll ie. What is your eCPM? $0 - $2 $2 - $4 $4 - $6 $6 - $8 $8 > etc
