其假设检验H0为

A、μ[img=~/QImg/2013-10-14-11-38-02/image025.gif]=μ[img=~/QImg/2013-10-14-11-38-02/image026.gif]
B、μ[img=~/QImg/2013-10-14-11-38-02/image025.gif]≠μ[img=~/QImg/2013-10-14-11-38-02/image026.gif]
C、μ=μ[img=~/QImg/2013-10-14-11-38-02/image039.gif]
D、μ≠μ[img=~/QImg/2013-10-14-11-38-02/image039.gif]
E、以上都不对
