One-Way ANOVA Is Applied to Independent Samples Taken from Four

Short Answer

One-way ANOVA is applied to independent samples taken from four normally distributed populations with equal variances. If the null hypothesis is rejected, then we can infer that: $\begin{array}{|l|l|}\hline A.&\text { all popul ation means are equal}\\\hline B.&\text {all population means differ. }\\\hline C.&\text { at least two population means are equal.}\\\hline D.&\text {at least two population means differ. }\\\hline \end{array}$
