Erm, just some statistical queries.. what about chebychev's inequality:
http://en.wikipedia.org/wiki/Chebyshev%27s_inequality
"No more than 1/k^{2} of the distribution's values can be more than k standard deviations away from the mean"
In this case it is 1/(3.7*3.7) which is 7%, and 24*7% is 1.75, so no more than 1.75 of the observables should be this far away. One deviation this large is perfectly expected from Chebychev's inequality.
Thanks,
Rob

Dear bfys-physics friend, This is to let you know that I collect comments to the paper below. To stimulate you to read it: we claim that the probability that the measurement is consistent with the Standard Model is only 0.5%. A local discrepancy of 3.7 sigma is observed.
