This question was "closed as too localized by cardinal, Benjamin Lim, The Chaz, did, Zev Chonoles" on May 8th. A statement below it said:
"This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet."
None of that makes the least bit of sense at all. To say it applies only to a certain geographic area is lunacy. It's a perfectly reasonable question. And the answer explains why the null distributions of certain p-values in hypothesis tests are what they are.
Why did this happen?
Later edit: Once again I find people saying that a poster is in the habit of posting bad stuff; therefore when the poster posts something good it should be down-voted and closed, and a false statement of why it was closed should be published.
That is wrong.
