One-Way ANOVA Is Applied to Independent Samples Taken from Three $n _ { 1 } =$

question 116

Short Answer

One-way ANOVA is applied to independent samples taken from three normally distributed populations with equal variances. The following summary statistics are calculated: $n _ { 1 } =$ 10, $\bar { x } _ { 1 } =$ 40, $s _ { 1 } =$ 5. $n _ { 2 } =$ 10, $\bar { x } _ { 2 } =$ 48, $s _ { 2 } =$ 6. $n _ { 3 } =$ 10, $\bar { x } _ { 3 } =$ 50, $s _ { 3 } =$ 4. The between-treatments variation equals: $\begin{array}{|l|l|}\hline \text { A. } & 460 . \\\hline \text { B. } & 688 . \\\hline \text { C. } & 560 . \\\hline \text { D. } & 183 . \\\hline\end{array}$
