We give a Grüss-type inequality which is a refinement of a result due to Dragomir and Agarwal. We also give its applications for the moments of random variables, guessing mappings, and Ozeki's inequality.

We shall obtain the best bound in Ozeki's inequality which estimates the difference of Cauchy's inequality. We also give an operator version of Ozeki's inequality which extends an inequality on the variance of an operator.

Extending the notion of a weakly positive operator introduced by Wigner, we define a weakly selfadjoint operator as the product of two selfadjoint operators, one of whose factors is positive, and show some facts on the operator.
