Answer
A scatterplot is drawn for the perch per pen and proportion eaten to observe the data.
None of the perch per pen are the explanatory variable so it is on the x-axis and the proportion eaten is the response variable so it on the y-axis.
The vertical spread of the points above each pen size shows the variation in the proportion of perch eaten by bass. The overall
pattern behind this variation is shown by the plot of mean proportion eaten for each of the pen size which is shown by the
linear pattern. This shows a clear positive association between number of prey present and proportion eaten by predators.
The relationship is approximately linear as shown in the plot attached.
