question 170

Short Answer

Compute and Interpret the Coefficient of Determination
-In a study of feeding behavior, zoologists recorded the number of grunts of a warthog feeding by a lake in the 15 minute period following the addition of food. The data showing the weekly number of grunts and the age of the warthog (in days) are listed below. Find and interpret the value of $\mathrm { R } ^ { 2 }$ .
$\begin{array}{cc}\hline \text { Number of Grunts } & \text { Age (days) } \\\hline 82 & 117 \\60 & 133 \\31 & 147 \\36 & 152 \\55 & 159 \\32 & 166 \\54 & 175 \\9 & 181 \\12 & 187 \\\hline\end{array}$
