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.
a)Re-express the dioxin concentration by taking the reciprocal square root of the data,then plot the re-expressed data as a scatterplot.
b)Determine the regression equation and correlation coefficient for the re-expressed data.
c)Use your model from part (b)to predict the dioxin concentration at a distance of 500 metres.
