Well, that's actually 2 one-tailed hypotheses you have included.

It's really easy:

- one-tailed hypotheses specify a certain direction. Eg. reading more books will improve children's reading abilities.

- two-tailed hypotheses don't specify and that it could go either way. Eg. reading more books will affect children's reading abilities.

Well, I think you're being too specific and people may assume that you are certain that it will go that way. It's like saying 'the faster the car, the quicker it takes to get there whereas the slower the car, the longer it takes to get there'. So basically, you are just repeating yourself.
