 You have to reject the null hypothesis, which is that there is no soul. You have to accept the alternative hypothesis that there is because you, in fact, are able to do that which the physical body cannot do. Well... That's the nature of the hypothesis testing. If you're wondering about that, I have to say that that's what all of science is out there doing. They're doing these hypotheses. They say, if this exists, then you must be able to do this X, Y, or Z with it.
