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.

$\begin{array}{|l|l|l|}
\hline \text { Diet } & \text { Gained weight } & \text { Lost weight } \
\hline \text { High Fat } & 79 & 21 \
\hline \text { Low Fat } & 30 & 69 \
\hline \text { Control } & 70 & 30 \
\hline
\end{array}$
-What proportion of mice in the experiment gained weight?

Quizplus · Accepted Answer

To find the proportion of mice that gained weight, add the number of mice that gained weight in all diets and divide by the total number of mice. Gained weight: $79 + 30 + 70 = 179$. Total mice: $100 + 100 + 100 = 300$. Proportion: $179 / 300 = 0.596$, which rounds to 0.60.
