Abstract
Stochastic Orders and inequalities are begin used at an accelerated rate in many diverse areas of probablitity and statistics.I n the Literature several concepts of stochastic ordering between random variables have been considered .They are useful in modeling for reliability and economics applications and as amathematical tool to prove important results in applied probablity(see Barlow and PROSCHAN(1981),alzaid(1988),ALZAID et al.(1991),Fagiuoli and pellery (1993),SHAKED and SHANTHIKUMAR (1994),KEBIR(1994),SHAKED and WONG(1997),belzunce et al.(1997))and BELZUNCE et al.(1999).
