A random sample of some of the heaviest carnivores on Earth was reviewed to determine if there is an association between the length (in meters) and weight (in kilograms) of these carnivores. Here are the scatter plot, the residuals plot, a histogram of the residuals, and the regression analysis of the data. Use this information to analyze the association between the length and weight of these carnivores.

A random sample of some of the heaviest carnivores on Earth was reviewed to determine if there is an
association between the length (in meters) and weight (in kilograms) of these carnivores. Here are the scatter
plot, the residuals plot, a histogram of the residuals, and the regression analysis of the data. Use this
information to analyze the association between the length and weight of these carnivores.
