-This red line came from p2, whose mean is different from p1's. We know that p2's mean is 5 greater than p1's (100). And red line (mean of a sample from p2, whose sample size (s.size) 100. So the truth is that we should deny null hypothesis, and accept the alternative (research) one. But, because of the value, m.treated.s we could not. We failed to find out the truth (ERROR). This kind of error is called Type I Error.
