Lawn Fertilizer
To test the effectiveness of three different types of lawn fertilizer,each type was applied to six different lawns.The same size patch of lawn was mowed for all 18 test units and the grass clippings were weighed.The weight in pounds are shown in the following table.
$$\begin{array} { | c | c | c | c | } \hline & \text { Fertilizer 1 } & \text { Fertilizer 2 } & \text { Fertilizer 3 } \\\hline \text { Lawn 1 } & 10.3 & 11.7 & \mathbf { 8 . 2 } \\\hline \text { Lann 2 } & \mathbf { 8 . 6 } & 12.0 & \mathbf { 8 . 9 } \\\hline \text { Lawn 3 } & \mathbf { 8 . 2 } & 9.3 & 10.7 \\\hline \text { Lawn 4 } & 10.6 & 10.5 & 9.3 \\\hline \text { Lawn 5 } & 9.1 & 9.8 & 10.4 \\\hline \text { Lawn 6 } & \mathbf { 8 . 2 } & 12.4 & 9.6 \\\hline\end{array}$$
