Multiple Choice

In comparing the two standard deviations below, what is the test value and what are the degrees of freedom that should be used? $$\begin{array} { | l | c | c | } \hline & \text { Standard Deviation } & \text { Number of values } \\\hline \text { Sample 1 } & 7 & 17 \\\hline \text { Sample 2 } & 2 & 25 \\\hline\end{array}$$

A) test value = 3.50, degrees of freedom = 17 and 25
B) test value = 3.50, degrees of freedom = 16 and 24
C) test value = 12.25, degrees of freedom = 17 and 25
D) test value = 12.25, degrees of freedom = 16 and 24
