Question 259799
My assistant is busy right now but maybe I can help... or did you mean assistance??

{{{M=Mean=45}}}
{{{S=Sigma=15}}}
In general,
{{{z=(X-M)/S}}}, where X is your raw data.

{{{X=29}}}
{{{ z=(29-45)/15= -1.067}}}
.
.
.
{{{ X=25}}}
{{{ z=(25-45)/15=-1.333}}}

Pretty straightforward, yes?

How about a quiz score of 47 and a quiz score of 40.
What would be the z scores for those?
