Assume Norm + ( m,s 2 ) be the distribution of the maximum value of
N
N stochastic variables distributed normally with mean m and variance s 2 .
Then for N = 4, 10, 30, each median value of Norm + (0,1) are,
N
approximately 0.9981, 1.4988, 1.9982, that are rounded down to
0.998, 1.498, 1.998, respectively. These are easy to remember as
1-e , 1.5-e , 2-e for N = 4, 10, 30 with e =0.002, thus possibly very useful
for your daily and social life. These numeric figures are calculated from
billions of Mersenne Twister psudo-ranom numbers using R language.
