Question

Find P(z < 3.47)Use the Normal table and give answer using 4 decimal places.

Answer 1

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

$P(z<3.47)=0.5+P(0From the standard normal table, P(0 < z < 3.47) = 0.4997. So,[tex]\begin{gathered} P(z<3.47)=0.5+0.4997 \\ =0.9997 \end{gathered}$

Final Answer: P(z < 3.47) = 0.9997
