Yurik74 That's a good one!
rhardin C is just as correct as B, so why is the answer only B? I see the "most accurate" part of the question, but something is either accurate or its not, and C is accurate from what I can see. Right?
pikusa SEE is not going to decrease with more observations if model is not correctly specified. So C is not always correct. B is just a rephrased definition of SEE.
chriswwu good point, pikuse. very subtle.
JZERMENO A little bit tricky...
