Researchers built a model to explore the relationship between a possum's total body length (in cm) and their skull width (in mm). They collected data from 104 possums in Australia and New Guinea. Researchers built a model to explore the relationship between a possum's total body length (in cm) and their skull width (in mm). They collected data from 104 possums in Australia and New Guinea. skull width = 23.771 + 0.38022*body length. Compute the residual for the possum in the sample who had a body length of 89 cm and a skull width of 56.8 mm. Round your answer to 1 decimal place
