6.(13) Standard of Proof Recall that (when the null hypothesis is that an accused person is innocent) a Type I error occurs when an innocent person is found guilty, and that a Type II error occurs when a guilty person is found innocent. The expected social cost of judicial error in a case equals the (probability of a Type I error times the social cost of a Type 1 eror) + (probability of a Type II error times the social...
