question 90

Short Answer

One-way ANOVA is performed on independent samples taken from three normally distributed populations with equal variances. The following summary statistics were calculated: $n _ { 1 } =$ 7, $\bar { x } _ { 1 } =$ 65, $s _ { 1 } =$ 4.2. $n _ { 2 } =$ 8, $\bar { x } _ { 2 } =$ 59, $s _ { 2 } =$ 4.9. $n _ { 3 } =$ 9, $\bar { x } _ { 3 } =$ 63, $s _ { 3 } =$ 4.6. The value of the test statistics, F, equals: $\begin{array}{|l|l|}\hline\text { A. } & 71.250 \\\hline \text { B. } & 0.322 . \\\hline \text { C. } & 21.104 \\\hline \text { D. } & 3.376 . \\\hline\end{array}$
