I collected data where two players interacted with two choices each, where a 2x2 table resulted when representing the game in strategic form. The 4 outcomes are (A, A) ; (A, B) ; (B, A) ; (B, B). My null hypothesis is that the outcome (B, B) is more likely in the treatment group (Treat==1) than in the control group (Treat==0). The control group has 14 subjects and the treatment 16. How could I test my null? I could perform the test both manually or on STATA.
