P-value. of a test is the . probability, computed supposing . H. 0. to be true, that the . test statistic. will take a value at least as extreme as that actually observed. Small . P-values. indicate strong evidence against . H. 0. To calculate a . P-value. we must know the . sampling distribution. of the . test statistic. when . H. 0. is true ... ................
