  1. Locomotive 77654 Test and CI for Two Proportions Sample X N Sample p 1 207 3133 0.066071 2 23 2902 0.007926 Difference = p (1) - p (2) Estimate for difference: 0.0581453 95% CI for difference: (0.0488681, 0.0674225) Test for difference = 0 (vs not = 0): Z = 12.28 P-Value = 0.000 Fisher's exact test: P-Value = 0.000
