Multiple Choice

Calculate the test statistic F 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. $$\begin{array} { l l } \mathrm { n } _ { 1 } = 13 & \mathrm { n } _ { 2 } = 12 \\\\\mathrm {~s} _ { 1 } ^ { 2 } = 17.248 & \mathrm {~s} _ { 2 } ^ { 2 } = 13.75\end{array}$$
