Abstract: Recently Stolarsky proved that the inquality

$\displaystyle \int_0^1 {g({x^{1/(a + b)}})\,dx \geq \int_0^1 {g({x^{1/a}})\,dx\int_0^1 {g({x^{1/b}})\,dx} } }$ ($ \ast$)

holds for every $ a,b > 0$ and every nonincreasing function on [0, 1] satisfying $ 0 \leq g(u) \leq 1$. In this paper we prove a weighted version of this inequality. Our proof is based on a generalized Chebyshev inequality. In particular, our result shows that the inequality $ ( \ast )$ holds for every function g of bounded variation. We also generalize another inequality by Stolarsky concerning the $ \Gamma $-function.
