Table 2

The probability of failing to produce an interval estimate in application of interval estimators (2) and (3) for the situations, in which the RR=1, 2, 4, 8, 32; the probabilities p_1. and p₁₁ equal: 0.01 and 0.005; 0.10 and 0.05; 0.50 and 0.25; 0.80 and 0.40; such that the combination of these parameters leads to a valid set of probabilities for which p_ij >0 for i and j=1, 2; and n=20, 50, 100, and 200
