    Statistics -> Normal distribution problem

    I've got to confess sir, you're a genius. Thanks for looking up "coefficient of variation" for me. Since it had the word variation, i assumed "related to variance". But clearly it was related to the standard deviation instead, as pointed by you and later confirmed by wiki. After running the...

    Statistics -> Normal distribution problem

    From part a. We know that the mean is 14.1, standard deviation 1.04536. So for the strength, the mean is 14.1*1.5 = 21.15. When it says 15% coefficient of variation, i am assuming that the variance is 21.15*0.15 = 3.1725. So the difference distribution, which also happens to be normal, ends...
