How many participants would you need to test to determine whether an interface component changed a users behavior? Have you seen this happen?

I'm curious to get other's thougths on a project I am working on.
I need to test whether users would change their response based on whether the information was presented in one way vs another way. For example, a value would be presented as 5 buttons where they could see all of them and click one OR the values could be presented in a slider with tick marks where they user could select one.
Question is do you think presenting the information in the two different ways could change what users would select and 2. how many particants would you use to check this theory?
