A Conservationist Wants to Know If the Water Level (In $\alpha = 0.05$

Short Answer

A conservationist wants to know if the water level (in meters) in Crab Lake is more or less variable than the water level in Gull Lake. If one tested the hypothesis that the levels are equally variable at $\alpha = 0.05$ , the hypothesis would be
$\begin{array}{|l|l|l|}\hline & \text { Crag Lake } & \text { Gull Lake } \\\hline \bar{r} & 44 & 33 \\\hline 8 & 3.9 & 2.4 \\\hline \| & 22 & 21 \\\hline\end{array}$
