Explanation:

Step1: Understand the notation

$z_{\alpha}$ represents the z - score such that the area to the right of it under the standard normal curve is $\alpha$. Here $\alpha = 0.09$.

Step2: Use the standard - normal table

We know that the total area under the standard - normal curve is 1. The area to the left of $z_{0.09}$ is $1 - 0.09=0.91$. Looking up the value 0.91 in the body of the standard - normal table (the z - table), we find the corresponding z - score.

Step3: Find the z - score

From the standard - normal table, the z - score corresponding to an area of 0.91 is approximately 1.34.

Answer:

1.34
