No, hit reduces the chance to miss. Its the highest priority roll. However now that i take another look at it i think my previous statement was abit incorrect. A blue quote on the subject is
"The way WoW calculates crit rate is over ALL attacks. Crit rate is not based on hits only. In other words, if you have a 5% crit rate, that 5% chance includes misses."
and im not entirely sure how to interpret this.
Edit: I believe what it means is that your miss chance includes a chance for your crits to miss, thus hit improves crit. i may be wrong though.
Yeah, I forgot to mention that Hit Rating reduces chance to miss rather than increase the chance to hit per se.
Ah, here we go from WoWWiki:
Miss
Dodge
Parry
Glancing Blow
Block
Critical hit
Crushing Blow
Ordinary hit

This is the table that governs a melee attack by a mob and a melee auto attack by a player.
The tables are laid out in descending order of the precedence of one attack result over another. That is to say, the entries at the top of the table take precedence over the entries below them. This precedence order is from Blizzard, and as such is accurate. What this table means is this:
* Every melee attack (except for yellow-damage special attacks dealt by players, as described in the next section) has a chance to miss, to be dodged, to be parried, to be blocked, to be a glancing blow, to be a critical, and to be a crushing blow. Anything left over is an ordinary hit.
* The chances listed in your general spellbook tab (for you to Dodge, Parry, or Block) are absolute percentages. If you have a listed dodge chance of 4.5%, then on average 4.5% of all melee attacks made against you by a mob of equal level will be dodged, not merely 4.5% of those melee attacks that didn't miss you.
* Some melee attacks have a 0% chance for some of these attack results; e.g., an auto-attack made by a player has a 0% chance of being a crushing blow, an attack made by a mob has a 0% chance of being a glancing blow, an attack made against a player without a shield has a 0% chance of being blocked, etc..
* For mob and white-damage melee attacks, there is no such thing as a blocked crushing blow, a parried crit, a missed glancing blow, etc.. All of these possible attack results are mutually exclusive.
* If the total chances of all the entries above the bottom of the table reach or exceed 100%, the attack cannot be an ordinary hit.
* If the total combined chance of a miss, dodge, parry, or block is 100% or higher (as in the case of a well-geared paladin using Holy Shield), not only can the attack not be an ordinary hit, the attack also cannot be a crit or a crushing blow.

So basically, the only time that increasing Hit Rating would result in increased occurence of Crits is if:
Crit Chance > 100 - (Miss% + Dodge% + Parry% + Glancing Blow% + Block%)
