1. Locomotive 77654 Test and CI for Two Proportions Sample X N Sample p
Difference = p (1) - p (2)
Estimate for difference:
95% CI for difference: ( , )
Test for difference = 0 (vs not = 0): Z = P-Value = 0.000
Fisher's exact test: P-Value = 0.000

2. Locomotive 77655 Test and CI for Two Proportions Sample X N Sample p
Difference = p (1) - p (2)
Estimate for difference:
95% CI for difference: ( , )
Test for difference = 0 (vs not = 0): Z = P-Value = 0.000
* NOTE * The normal approximation may be inaccurate for small samples.
Fisher's exact test: P-Value = 0.000
