    the third statistics independent with sample mean and variance

    As we know, if X1, X2 ... XN are IID normal distribution, then the mean of the samples and the variance of the samples are independent. My question is, could we use X1, X2 ... XN to construct the third statistics, which independent with the sample mean and variance.

    Independence of Bivariate Continuos RV's.

    By the two definitions of independence for bivariate continuous RVs: (1) F(x,y)=F_X(x)F_Y(y) and (2) f(x,y)=f_X(x)f_Y(y). Prove that these two are equivalent. That is: prove that (1) implies (2) and that (2) implies (1). I tried to differentiate for one and integrate for the other.
