**cat**, Wednesday, October 13, 2010 at 7:05pmhey cat:

thank you for the information. so clarify i would just plug in the test scores such as 13 and 59 for the x value and 43 for mean with 17.0 for the standard deviation to come up with the following :

z=(13-43)/17.0= 10.47058824 to round off to 10.0?

z= (59-43)/17.0=56.47058824, round off to ?

please coonfirm and show where i went wrong. thank you very much.
