For the samples summarized below, test the hypothesis, at $\alpha = 0.05$ , that the two variance are different.
$\begin{array}{l|cc} & \text { Sample 1 } & \text { Sample 2 } \\\hline \text { Sample Std. Deviation } & 4.1 & 2.7 \\\text { Sample size } & 10 & 20\end{array}$

• A) Accept the hypothesis because the test value 2.31 is less than the critical value 2.35
• B) Reject the hypothesis because the test value 2.31 is less than the critical value 2.88.
• C) Accept the hypothesis because the test value 5.32 is greater than the critical value 2.77.
