Given μ = 1000, σ = 50:
calculate the 99% percentile ranking.
Setup our z-score
The z-score formula is:
| z = | x - μ |
| σ |
Rearranging this formula, we get:
x = μ + zσ
Find z-value for 99%:
We get a z-value of 2.326
Excel or Google Sheets formula:
Excel or Google Sheets formula:=NORMINV(0.99,1000,50)Evaluate z = 2.326, μ = 1000, σ = 50
x = 1000 + 2.326(50)
x = 1000 + 116.3
x = 1116.3

What is the Answer?
x = 1116.3
