【Abstract】 In this paper,the mean check of the statistical hypothesis H 0:μ 1=μ 2=…=μ n is discussed.Here,sample population X 1,X 2,…,X n are irrelevant each other and satisfy the normal distribution.Under the condition of σ 1 2=σ 2 2=…=σ n 2 and σ j 2(j=1,2,…,n) is unknown,the statistic T n and T′ n are constructed,with which the quick check of the suppose H 0 can be calculated.更多还原
