No answer provided yet.I believe what you might be looking for is the amount of area under the normal curve for each of the sigma values. Lets assume these are the 2-tailed areas (not 1-sided). We can look them up using a normal table of values or the z-score to percentile calculator or we can use the Excel function =NORMSDIST() and enter 1,2,3,4,5 and 6We get the values :

- .8413
- .97725
- .99865
- .999968
- .99999971
- .99999999901
