Clearly not. The vast majority of people responding to this problem usually want to pull the lever, murdering an innocent who would otherwise have lived through the day - an utilitarian perspective that holds that by default it's best to maximize the amount of lives saved. It's difficult for those of us that would argue that every life is valuable, and that, not being god, the bystander does not have the right to make this call. The bystander did not place the runaway trolley there, nor are they responsible for the people who are tied to the tracks.

I would ask the person who is (in most of these scenarios) on the diverted tracks what they want me to do. They have the right to make this decision, since they are masters of their own life.
