A grass seed company conducts a study to determine the relationship between the density of seeds planted (in pounds per 500 sq ft)and the quality of the resulting lawn.Eight similar plots of land are selected and each is planted with a particular density of seed.One month later the quality of each lawn is rated on a scale of 0 to 100.The sample data are given below. $$\begin{array} { c | c }
\text { Seed Density } & \text { Lawn Quality } \
\hline 1 & 30 \
1 & 40 \
2 & 40 \
3 & 40 \
3 & 50 \
3 & 65 \
4 & 50 \
5 & 50
\end{array}$$ Using a 10% level of significance,is there evidence of an association between seed density and lawn quality?
