How to solve question 5

269 / 446 110% + where 1 A J. Interpret 5. Let X e {0, 1} be a binary treatment variable and let (Co, C1) denote the corresponding potential outcomes. Let Y = Gx denote the observed 262 16. Causal Inference response. Let Fo and F1 be the cumulative distribution functions for Co and C1. Assume that Fo and F, are both continuous and strictly increasing. Let 0 = mj - mo where mo = Fo '(1/2) is the median of Co and m1 = FF (1/2) is the median of C1. Suppose that the treatment .X is assigned randomly. Find an expression for e involving only the joint distribution of X and Y
