Explanation:


Use a <a href="http://www.stat.ufl.edu/~athienit/Tables/Ztable.pdf">standard normal table</a> (z table), to locate the value 0.9400 or something close to it. The closest value in the table is 0.9406 which happens when z = 1.56 (see page 2; read the row 1.50 and the column 0.06)


This means

*[Tex \Large P(Z < 1.56) \approx 0.9406]

So the value z = 1.56 is the approximate critical z value that cuts off the bottom 94% from the top 6%</font>
