In this blog post, we will learn how to find the z-score for having an area 0.09 to its left of the standard normal curve.

To find the z-score for a given area, check if the area is left to mean or right to the mean. Based on that, we will use either a negative z-table or a positive z-table.

## Find the z score for having area 0.09

Let’s find out the z-score for a given area using the below step-by-step guide.

**Step 1:** Symmetric property of the standard normal curve indicates 50% area lies to the left of the mean and 50% of the area lies to the right of the mean.

**Step 2:** Compare the given area with 0.50.

Given area = 0.09 < 0.50,indicates area is left to the mean i.e. negative z-score.

**Step 3:** Choose negative z-table as required z-score is negative.

**Step 4:** Draw the normal distribution for the given area = 0.09

**Step 5:** Trace the closest value to the given area=0.09 in the z-table.

**Step 6:** Note the corresponding row and column values from z-table

**Step 7:** Combine the numbers to calculate the required z-score.

Z-score = row value + column value (as per z-table)

-1.3 + 0.04

Z-score = -1.34

**Result:** The Z-score for the area of 0.09 is -1.34.
