四组均数比较的方差分析,其备择假设H[img=~/QImg/2013-10-14-10-46-38/image010.jpg]应为

A、μ[img=~/QImg/2013-10-14-10-46-38/image010.jpg]=μ[img=~/QImg/2013-10-14-10-46-38/image013.jpg]= μ[img=~/QImg/2013-10-14-10-46-38/image079.jpg]= μ[img=~/QImg/2013-10-14-10-46-38/image080.jpg]
B、μ[img=~/QImg/2013-10-14-10-46-38/image010.jpg] ≠μ[img=~/QImg/2013-10-14-10-46-38/image013.jpg]≠μ[img=~/QImg/2013-10-14-10-46-38/image079.jpg]≠μ[img=~/QImg/2013-10-14-10-46-38/image080.jpg]
