    What is it with these anachronistic instructors who insist on doing these things by hand?. Tell your instructor I said to look at the calendar. It's 2008, not 1908. Does he/she want you to calculate square roots by hand as well?.

    Anyway, you can google and find some things. Here is what wiki has to say about it.

    Well

    the instructor doesn't know how to do it in Minitab. So he wants the students to do it manually so that the answers match!

    Cheers
