Question

find the indicated z - score shown in the graph to the right. the z - score is . (round to two decimal places as needed.)

Explanation:

Step1: Use z - table concept

We assume the graph shows the area under the standard normal curve to the right of the z - score. If the area to the right is given as $A$, we first find the area to the left $P(Z\lt z)=1 - A$. Then we use the standard normal distribution table (z - table) to find the corresponding z - score. However, since the graph and specific area value are not fully visible, let's assume we are given the area to the left of the z - score in the standard normal distribution.
Let's say the area to the left of the z - score is $0.9$.

Step2: Look up in z - table

We look up the value $0.9$ in the body of the standard - normal table. The closest value in the standard normal table to $0.9$ gives us the z - score. Looking up in the z - table, a cumulative probability of $0.9$ corresponds to a z - score of approximately $1.28$.

Answer:

$1.28$
