log transformation

[Richard M. Barton]

Forgive what may be simplistic questions:

Suppose Y does not appear to be normally distributed, but Z=ln(Y) does.
I do a linear regression of Z on X, which is dichotomous (0,1).

1) In simple terms, what does the unstandardized regression coefficient b tell me about the relationship between X and Y?

2) Is {e raised to the b} interpretable in terms of X and Y?

3) Is there some other transformation of b that makes the relationship between X and Y easily interpretable?

Thanks for your help.
