 Annual Appeal: Please make a donation to keep the OEIS running. In 2018 we replaced the server with a faster one, added 20000 new sequences, and reached 7000 citations (often saying "discovered thanks to the OEIS"). Other ways to donate

 OFFSET 0,1 COMMENTS 0.75 percentile of the normal probability distribution function. In a bilateral sense, normally distributed random values x are equally likely to fall inside the interval (-a*sigma, +a*sigma) as to fall outside, "a" being this constant. - Stanislav Sykora, Nov 08 2013 LINKS Stanislav Sykora, Table of n, a(n) for n = 0..9999 Stanislav Sykora, PARI/GP scripts for NormalErrorFunctions.
