Neither System 1 nor System 2 showed a significant difference between selection of translations provided by the trained or untrained system: chi-squared tests did not detect a significant difference between number of responses favoring the trained system and number of responses favoring the generic system (p = 0.1948 and p = 0.26, respectively, for the two systems).
a chi-squared test indicated a significant preference for System 3, which was chosen 35% more often than the generic system (p = 0.0048).
