The left graph is the density for control group (X = 0), 0.9*Weibull(5.07, 93.52)*I(X ≤ 130) + 0.1*Weibull(5.40, 100.06)*I(X > 130), and the right graph for treatment group (X = 1), 0.6*Weibull(5.07, 93.52)*I(X ≤ 130) + 0.4*Weibull(5.40, 100.06)*I(X > 130), where P(Y > τ|X = 1) ≠ P(Y > τ|X = 0), μ (Y |Y > τX = 1) = μ (Y |Y > τX = 0), and μ (•) denotes the population mean of (•). τ is 90th percentile of the all observations in treatment and control groups.
