In this blog post, we will discuss how to find the zscore for having an area 0.09 to the left of the standard normal curve.
To find the zscore for a given area, check if the area is left to the mean or right to the mean. Based on that, we will use either a negative ztable or a positive ztable.
How to Find the z score for having an area 0.09
Let’s find out the zscore for a given area of 0.09 using the below stepbystep 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 the area is left to the mean i.e. negative zscore.

Step 3: Choose a negative ztable as the required zscore 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 ztable.

Step 6: Note the corresponding row and column values from ztable

Step 7: Combine the numbers to calculate the required zscore.
Zscore = row value + column value (as per ztable)
1.3 + 0.04
Zscore = 1.34
Result: The Zscore for the area of 0.09 is 1.34.
Conclusion
I hope the above article to find the zscore for a given area 0.09 is helpful to you.
