A grass seed company conducts a study to determine the relationship between the density of seeds planted (in pounds per 5000 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 1 to 100. The regression analysis is given below. Is there EVIDENCE of an association between seed density and lawn quality?
