Find the Critical Value $$\mathrm { F } _ { 0 }$$

Multiple Choice

Find the critical value $$\mathrm { F } _ { 0 }$$ to test the claim that $$\sigma _ { 1 } ^ { 2 } = \sigma _ { 2 } ^ { 2 }$$ Two samples are randomly selected from populations that are normal. The sample statistics are given below. Use $$\alpha = 0.02$$ $$\begin{array} { l l } \mathrm { n } _ { 1 } = 13 & \mathrm { n } _ { 2 } = 12 \\\\\mathrm {~s} \frac { 2 } { 1 } = 7.84 & \mathrm {~s} _ { 2 } ^ { 2 } = 6.25\end{array}$$
