WebThe p-value for the Fisher's exact test is 0.011 for a nondirectional test. So the epxeriment provided strong evidence that ECMO really is different from CMT. Furthermore, the P-value for a directional test (Ha: ECMO > CMT) is 0.011 (happen to the same as the nondirectional test), so we could also conclude that ECMO really is better than CMT.
