Hi,

Hoping to get some insight into how to plot variance to mean along with graphing the normal distribution.

Please excuse the clumsy definitions/descriptions.

I have three mumbers which I'm hoping to be able to use to graph a normal distribution

Mean = 87.85

Std.Dev = 8.38

Entire sample size = 10,000,000,000

The other thing I need to do is understand the expected deviation from mean after X number of results, which might be as little as 5% of the Entire sample needed to establish the mean....

Any guidance appreciated
