Student advisors are interested in determining if the variances of the grades of day students and night students are the same. The following samples are drawn: $$\begin{array} { l l }
\text { Day } & \text { Night } \
n _ { 1 } = 25 & n _ { 2 } = 31 \
s _ { 1 } = 9.8 & s _ { 2 } = 14.7
\end{array}$$ Test the equality of the variances of the populations at 95% confidence.
