Geometric and weighted mean

[metcalfdds]

Please see pg 230 ("Ch 11 Statistics 1Var app") of the "HP Prime Graphing Calculator" user's guide. Unfortunately, the method is not actually labelled "weighted mean"--that would have been helpful!

Basically: Apps -> Statistics 1 var -> enter x values in list D1 and frequencies in list D2 -> check with [Symb x] button that "D1" and "D2" are entered in the "H1" fields -> return to lists with [Num] button -> push "Stats" soft key to get the weighted mean, variance, etc.
