The question is: Given a mean of 25 and a standard deviation of 2.3, what is the z-score of a data value of 29? 1.8 1.73 -1.7 1.74
OpenStudy (anonymous):
First of all, I don't even understand the formula they gave me for the z-score so I have no idea where to start..
OpenStudy (anonymous):

OpenStudy (anonymous):
