The 3rd standard deviation is different though........99.7%.........................25...............as in 25 primes in the 1st 100 #'s.....................I seem to be making this stuff even to myself sometimes.................9 + 9 + 7 = 25.................two numbers above the decimal.......one below it..........above and below.........crests and troughs............................also the 3rd standard deviation is the 1st one involving a decimal..............






68%...................6 + 8 = 14....................9 + 5 = 14..............two 14s....................which is how the square root of 2 starts out.....................28...........the primes in the pf...........add up to 28...............a non prime.............the non primes..........add up to a prime..............37.........symmetry..........balance..........half of 28 is 14.......................two of them.........like wow indeed.........

If a data distribution is approximately normal then about 68 percent of the data values are within one standard deviation of the mean (mathematically, μ ± σ, where μ is the arithmetic mean), about 95 percent are within two standard deviations (μ ± 2σ), and about 99.7 percent lie within three standard deviations (μ ± 3σ ...
