The number of yards of line reeled in 10 seconds was recorded for each. The other group was tested together under conditions of competition; the one who reeled the most line got to keep the reel. The following summary statistics were obtained. $\begin{array}{lcc} & \text { Individuals Group } & \text { Competition } \\\Sigma X& 192 & 288 \\\Sigma \mathrm{X}^{2} & 3347 & 7308 \\ N & 12 & 12\end{array}$
