A p-value is the probability of a result of that magnitude occurring in the data, if the null hypothesis is true - we could call that the probability of the data, given the. The alternative hypothesis is the one you would believe if the null hypothesis is concluded to be untrue. The critical value depends on the probability you are allowing for a Type I error.
