Dioxins are a class of long-lived and highly toxic pollutants.The topsoil concentration of dioxins in parts per million (ppm)are shown in the table below as a function of the distance from the dump. $\begin{array}{l}
\begin{array}{l|l}
&\text { Dioxin }\
\text { Distance from } & \text { concentration } \
\text { dump (metres) } & (\text { ppm) } \
\hline 21 & 423 \
\hline 42 & 235 \
\hline 49 & 140 \
\hline 79 & 65 \
\hline 102 & 35 \
\hline 128 & 45 \
\hline 157 & 22 \
\hline 204 & 14 \
\hline 248 & 9
\end{array}
\end{array}$ Re-express the dioxin concentration by taking the reciprocal square root of the data,then plot the re-expressed data as a scatterplot.
