Question about popularity of software!!

i'm new fish in Mac.
Now my company wanna do some researchs on usage on Mac.

I would like to ask some questions:
Q1) Which version of Safari is the most popular?
Q2) Which version of Firefox is the most popular?
Q3) Which version of JVM is the most popular?

Many thx!!!!

I doubt anyone can tell you which particular version of a browser is most popular. You could do a survey, but web surveys are notoriously inaccurate. The best you can really hope for is a breakdown of percentage usage by browser (regardless of version number).

The answer is probably "the most current version" in each case.

So, for Safari, that would be 3.1.

For Firefox, that would be 2.0.0.14

For JVM, I don't know, since I have never used it.

really thx a lot!!
