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 ...

This test statistic is so large that by Table A the P-value is very close to 0 (by calculator, P-value = 0.00014). Conclude: A P -value of 0.00014 is much less than _ = 0.05, so we reject H 0 . We have sufficient evidence to conclude that the proportions of people who experience adverse reactions to acetaminophen and ibuprofen are different.
