Statistics

I can say with 95% confidence, that the mean number of days it will have taken me to complete my statistics class will be between the interval of (35, 50) days.  And then I plan to promptly purge my brain to make room for other useless stuff I have to learn this summer.
I can also say with 100% confidence that I hope I never have to go more in depth in statistics than I have.  You know, because in the book it tells you that a horrible, abstract, complicated procedure exists, "but it is outside the scope of this class".  When that happens I utter grateful praises that I don't have to learn it.  (But look there, I have improperly used the term confidence in that last example.  There's not even a quantitative variable at all! SHEESH.)
