We can observe that z-test shows that the IT2PE and IT2XB indices of validation are lower than the z-critical value that is equal to -1.645 with a significance level [alpha] of 0.05, whose z-values confirm the acceptance of the alternative hypothesis posed in (15) for these indices of validation, demonstrating that the IT2FPCM algorithm is better than IT2FPCM algorithm for the data clustering of the Iris Flower dataset using the IT2PE and IT2XB indices.
