WebNext, Fisher’s exact test results are displayed. Here also, the p-value (0.044) is lower than the significance level 0.05. Fisher’s exact test also leads to a rejection of the null hypothesis. Notice that the p-value obtained under the Chi-square test is slightly lower than the one associated to Fisher’s exact test.
