An investigation of the relationship between traffic flow (measured in cars per day) and lead content (measured in micrograms per gram of dry weight) in the bark of trees near the highway yielded the following summary statistics: Sample Mean Sample Standard Deviation Lead Content (micrograms per gram dry weight) 680 240 Traffic Flow (cars / day) 1750 800 The correlation between lead content and traffic flow was found to be r = 0.6 and a scatterplot showed the form to be linear.
