Question

find the area of the indicated region under the standard normal curve.
-1.13 0 2.03
a. 0.0212
b. 0.1292
c. 0.1504
d. 0.8489

Explanation:

Step1: Find left - side area

We use the standard normal table. The area to the left of $z = - 1.13$ is $0.1292$.

Step2: Find right - side area

The area to the left of $z = 2.03$ is $0.9788$. So the area to the right of $z = 2.03$ is $1 - 0.9788=0.0212$.

Step3: Calculate total shaded area

The total area of the shaded region is the sum of the area to the left of $z=-1.13$ and the area to the right of $z = 2.03$. So $0.1292+0.0212 = 0.1504$.

Answer:

C. 0.1504
