I presume you do not have a doctorate in the shoe manufacturing either. If you looked at the original thread, I simply stated that AE is on the left hand side of the distribution of the quality (which, by the way, is probably not normal, but rather Gamma or Beta, the way I see it), Goodyear welted shoes. Do you think I am not qualified enough to make this statement? If so, I will continue to improve my knowledge.
I strictly mentioned about my background in stats in respect to the following (hope this was not too obnoxious):
300+ dollars for shoes is not cheap...Some of the seconds sales like the 2 for 250 etc are probably getting there though.
I don't think you understand how a normal distribution works.
