Below and also attached is a TI-83 version of Allan Rossman's Minitab
Macro's for problem 7-4 of Workshop Statistics.. The attached file can be
imported directly by a TI-83 Link into the Mac (IBM also ??) using the
Tools/Import Ascii Program Menu.

-------
I tried to have it also plot the regression line but cannot get a and b of ax
+ b into Y1 (trying to use strings). Help - can you figure out how to do
this?
