Resumen
Let X1,…,Xn be independent random variables such that Xi has Weibull distribution with shape parameter a and scale parameter ?i, i=1,…,n. Let X1*,…,Xn* be another set of independent Weibull random variables with the same common shape parameter a, but with scale parameters as ?*=(?1*,…,?n*). Suppose that ??m?*. We prove that when 0
