I have read that the nose-tip rotation for a woman should be 95-105. I have also read that it should be 105-115. Which is right?

Rather than wory about the exact degree of angle of rotation of the tip rotation, it's more important not to over rotate the tip. Over rotation of the tip might look fine from the side profile, but will look very piggish from the frontal profile. Rhinoplasty is an art, and it is very important to produce a naturally appearing nose that does not look operated upon

The range of 95-105 degrees is generally a good rule of thumb and 105-115 would, in most people, be excessive. That angle depends on the length of the face, the height of the individual and some other facial parameters. The taller you are the less is that angle and a short individual could easily tolerate an angle of 105-110.  You should get a formal consultation with a Rhinoplasty surgeon who could answer your question more intelligently.
