Does anyone have a link to the chart that you use to find the probabilities of z-scores? Mine is not in my book.
A question like:
P(-2.02<z<0.58)
How do you go about handling that?
Firstly the chart does not work for all values.
You need to simplify that.
$\displaystyle P(-2.02<z<.58)=P(-2.02<z<0)+P(0<z<.58)$
Now,
$\displaystyle P(0<z<.58)$ you can find by chart.
And,
$\displaystyle P(-2.02<z<0)=P(0<z<2.02)$ because the normal curve is symetrrical. And then use the chart.
