Basic Math

Could you please explain to me when I should use the twoproportion tests?

A two proportion f test tests variance/standard deviation. So ifit is testing how much the two proportions vary then isn't it doingwhat a linear regression t test does?

Whats the difference between a linear regression t test andgoodness of fit test statistic?

Is there such thing as a two proportion chi squared test or isthat just an f test?

The only difference between a two proportion t test and a twoproportion z test is the knowing of a population standard deviationso that is good.

As you can see I'm all jumbled up.
