Supplements

The supplements come from many different places.  Different people use slightly different notations.  For example, some use X-bar for the sample mean; others use M.  This is like listening to someone with an accent who is speaking.  A bit odd at first, but with a little effort, the meaning is clear.  The supplements give you another look at the same thing we do in class and sometimes a bit of extra information.
