1 00:00:00,000 --> 00:00:06,000 And now, let me play a trick on you. I want to take A-B. So I'm subtracting A from B. 2 00:00:06,000 --> 00:00:09,000 Think of it as playing golf all the way over, 3 00:00:09,000 --> 00:00:13,000 picking up the ball, and playing the ball back to where you started. 4 00:00:13,000 --> 00:00:19,000 What do you think the µ‘ will be and what do you think the σ‘² will be? 5 00:00:19,000 --> 00:00:21,581 I'm appealing to intuition here.
