Consider an experiment in which adult laboratory mice were fed one of three diets: high fat, low fat, and a control diet. The mice were weighed, received these diets for 2 weeks, and then were weighed again. The table below shows the results of the experiment.

$\begin{array}{|l|l|l|}\hline \text { Diet } & \text { Gained weight } & \text { Lost weight } \\\hline \text { High Fat } & 79 & 21 \\\hline \text { Low Fat } & 30 & 69 \\\hline \text { Control } & 70 & 30 \\\hline\end{array}$
-To determine whether there appears to be a statistically significant relationship between diet and weight gain or loss we would conduct a ?² analysis. When performing this analysis, which of the values below is closest to the contribution to the ?² statistic from the "low fat : lost weight" category?
