Is there any association between left-to-right languages and right hand dominance, and vice versa?

Maybe not anymore, but was there ever any evidence that languages that were created and written right-to-left were done so by primary left handed people?

Nope. Hand-dominance is not correlated with writing systems. Even though there is some variation in the world (although it is difficult to judge because more conservative cultures that value conformity still often "encourage" lefties to use their right hand) the vast majority of humans everywhere are right handed. So if they were correlated, we'd expect NO variation in the direction of text.

As an aside, hand-dominance *does* have an impact on language-lateralization in the brain however.  That is, the language centre is usually in the left hemisphere of the brain, but a small number of people have it lateralized on the right. The proportion of people that are right-lateralized is slight higher for the left-handed population than the right.  Just to be clear because it's easy to warp that statement---the vast majority of left-handed people still have their language centre on the left side. It's just that the small percentage of right-lateralized left-handers is slightly higher than the small percentage of right-lateralized right-handers.
