Question

find the probability of z occurring in the indicated region. click here to view page 1 of the standard normal table. click here to view page 2 of the standard normal table. a. 0.0228 b. 0.0401 c. 0.9599 d. 0.0668

Explanation:

Step1: Recall standard - normal table property

The total area under the standard - normal curve is 1. The standard - normal table gives the area to the left of a given $z$ - value.

Step2: Find the area to the left of $z = 1.75$

Looking up $z=1.75$ in the standard - normal table, the area to the left of $z = 1.75$ is $A_{left}=0.9599$.

Step3: Calculate the area to the right of $z = 1.75$

The area to the right of $z = 1.75$ (the indicated region) is $A=1 - A_{left}=1 - 0.9599 = 0.0401$.

Answer:

B. 0.0401
