Given:
Given the region z < 3.47.
Required: P(z < 3.47)
Explanation:
Graph the region z < 3.47.
The probability P(z<3.47) can be written as
[tex]P(z<3.47)=0.5+P(0From the standard normal table, P(0 < z < 3.47) = 0.4997. So,[tex]\begin{gathered} P(z<3.47)=0.5+0.4997 \\ =0.9997 \end{gathered}[/tex]Final Answer: P(z < 3.47) = 0.9997
