Question

Find the z-value so that the area to the left of z (shaded in the picture) is 0.0322.

Answer 1

The z-value so the area to the left of z is 0.0322, can be determined from the z-value chart.

The area between z=0 and the given z value can be determined as,

`\begin{gathered} A=0.5-0.0322 \\ =0.4678 \end{gathered}`

The corresponding z-value from the chart is z=-1.85.
