Rivers in North Carolina contain small concentrations of mercury that can accumulate in fish over their lifetimes. The concentration of mercury in fish tissue can be obtained by catching fish and sending samples to a lab for analysis. A study was conducted on fish from the Waccamaw and Lumber Rivers to investigate mercury levels in tissues of largemouth bass. At several stations along each river a group of fish were caught, weighed and measured; in addition a filet from each fish was sent to a lab so that the tissue concentration of mercury could be determined. In all, 171 fish were caught at 15 different research stations along the Waccamaw and Lumber Rivers.

A scatterplot of length vs. weight for these fish is shown below.



Is it appropriate to compute the correlation for these two variables? Indicate below whether or not each condition has been satisfied.

Quantitative Variables Condition: (This means that both variables are quantitative.) Straight Enough Condition: (This means that the data appears to have a linear association.) Outlier Condition: (This means that there are not any outliers.)
