Question 865385
mean: mu = 2.94 (the symbol commonly used is mu = {{{mu}}})
standard deviation: sigma = 0.19 (the symbol commonly used is sigma = {{{sigma}}})
 

Raw Score: x = 3.04


-------------------------------------------------------


Z-score


{{{z = (x-mu)/sigma}}}



{{{z = (3.04-2.94)/0.19}}}



{{{z = 0.10/0.19}}}



{{{z = 0.52631578947369}}}



So the z-score is approximately z = 0.52631578947369



Round that accordingly if you need to (ex: if they want 2 decimal places, then don't forget to round to z = 0.53)
