0:00:00.000,0:00:06.000 And now, let me play a trick on you. I want to take A-B. So I'm subtracting A from B. 0:00:06.000,0:00:09.000 Think of it as playing golf all the way over, 0:00:09.000,0:00:13.000 picking up the ball, and playing the ball back to where you started. 0:00:13.000,0:00:19.000 What do you think the µ‘ will be and what do you think the σ‘² will be? 0:00:19.000,0:00:21.581 I'm appealing to intuition here.
