I'm trying to figure out what is the probability of a unit traveling greater than X given my data set. I am testing what is the % chance of the distance being greater on 1 try.

Here is some info about the data set:

Mean Travel Distance: 33.8

Median Travel Distance: 25

Standard Deviation: 31.3

Sample Size: 2139

Max Distance: 192

Min Distance: 0

I was using the below equation, but I do not know if it is the right function because the data is skewed right instead of a normal distribution:

=1-NORM.DIST(Travel Distance Being Tested,Mean,Standard Deviation,TRUE)

Should I be using a different function based on my data set?
