1) The discussion was about if C.C. worsen the results comparing with the raw calculation. IT DID NOT.
2) The two normal approximations have rather different accuracies (they ARE NOT slightly different contrarily Bob said).
______Relative errors (absolute values):
______ Not using C.C.___ (282-156)/156 = 35.9%
_________ using C.C.___ (144-156)/156 = 7.7 %
Therefore
______this last one procedure improves almost FIVE TIMES the result. To use it is an indisputable MUST.
