Does the book (or any other resource for that matter) provide instruction on how to assign good ranges?

For example, for a certain set of conditions (ie buyin, blind level, 9-handed, etc), an UTG 3x raise is usually a range of (AQ+, TT+).

I guess taking what HOH tells you that should play as actual villain ranges can help in that regard but are we assuming that everyone has read HOH and actually plays that way?

Or is the answer simply experience and observation?

Don't get me wrong, I know a book can't be that precise but any sort of general rules would be a good place to start.
