Abstract: We propose two exact p-values of two commonly-used test statistics for testing the superiority under Poisson populations. We show that, the computationally-intensive confidence-set p-value involves at most a supremum search over a closed interval of a single argument. On the other hand, the estimated p-value has adequate performances empirically.
