Hi,

re TY the NORMDIST function can be accessed in an excel worksheet:

1. click on a Cell(Space) 

2. Click "Insert"(up at the top)  (function)

3. chose Statistical /NORMSDIST

4. type in z -value

5. Hit OK

using Excel NORMSDIST function:

P (-2.25 < z <1.25) = NORMSDIST(1.25) - NORMSDIST(-2.25) = .8944 - .0122 = .8822
