Thesis/hypothesis?

do u think my hypthesis is good? how can i make it sound better? is there any stuff i could add that could add a little discussion to it? does it cleary answer my thesis question?

this is my thesis:
Is there a relationship between watching violence on T.V and committing violence?

this is my hypothesis:

I strongly believe that TV violence does affect people in committing violence in the outside world. Children, especially, can’t tell the difference between what is real or fiction. Exposure to TV violence increases aggression among children and adults because violence increases excitation. As a result, people who are exposed to TV violence are more prone to committing violence.
