Question

Find the area of the indicated region under the standard normal curve.

Answer 1

Finding z-score value of -1.3 to the left, we have the table

With these we have P(z < -1.3) = 0.09680

Since the shaded region is greater than -1.3, then the area is calculated as

`\begin{gathered} P(z>-1.3)=1-P(z<-1.3) \\ P(z>-1.3)=1-0.9680 \\ P(z>-1.3)=0.9032 \end{gathered}`

Therefore, the area of the indicated region is 0.9032.
