Given:
A graph is given with standard normal curve to the left of z=-0.50
Required:
Shade the region under the standard normal curve to the left of z=0.50
Explanation:
The region under the standard normal curve to the left of z=-0.50 is shown right for the area under the standard curve is 1
[tex]\begin{gathered} P(z\leq-0.50)=\phi(-0.50)=\text{ 1-}\phi(0.5) \\ \\ =1-0.6915=0.3085 \end{gathered}[/tex]
Required answer:
Shaded region shown in above graph
