Double Negatives and Statistics

Don’t use no double negatives, they say.

In fact, you shouldn’t never use no triple negatives.

But the AP Statistics review book I have tops them all with this following sentence:

There are two types of possible errors: the error of mistakenly rejecting a true null hypothesis and the error of mistakenly failing to reject a false null hypothesis.

(Barron’s AP Statistics, 5th Edition, page 356, referring to false positives and false negatives.)

By the way, today was the AP Statistics test. I wasn’t enrolled in the course, but I think I did just fine on it.
