I'm confused.  I'm human, I may be an instructor, but that does not mean
I don't mess up.  From time to time I make calculation errors or coding
errors - even with simple things like t-tests.  I want to catch these
before I incorrectly tell a student that they are wrong.  Are you
asserting that if I make mistakes I should not teach, or are you just
joking with me?
