If the minimum wage is increased $4, the competing explanations seem to be:

1. Change in unemployment is normally distributed with mean 0% and standard deviation 0.606%.

2. Change in unemployment is uniformly distributed between 1% and 10%.

I don't really agree that "(1) vs (2)" is a particularly good formulation of the original question ("Would raising the minimum wage by $4 lead to greater unemployment?"). But if it were, how would the math work out?

If we observe that unemployment increases 1%, then yes, that piece of evidence is very slightly in favor of explanation (1). This doesn't feel weird or paradoxical to me. But surely we wouldn't want to decide the matter based just on that one inconclusive data point? Instead we would want to look at another instance of the same situation. If in that case an increase of, say, 6% would (almost) conclusively settle the matter in favor of (2), and an increase of, say, 0.8% would (absolutely) conclusively settle the matter in favor of (1).
