I have come across a few hypothesis questions where the QBank answer actually did not assume the contrary to the fact being tested. Such as in:
“A bottler of iced tea wishes to ensure that an average of 16 ounces of tea is in each bottle…” (Schweser question ID 22960)
What is wrong with assuming Ho:=mean NOT equal to 16 and Ha:= mean IS equal to 16?
Is Schweser just plain wrong or am I getting my head mixed up?作者: dontknow1987 时间: 2013-4-16 09:49
Yes, that was the question. All right, thanks, thats the knock on my head I needed right now. All clear now.
Damn, if someone would have told me two weeks ago I would be struggling with such basic stuff I would have him committed
