A biologist is studying the relationship between the mass
of brains found in mammals taken from a forest and the
body mass of the mammals. A sample of 14 such
mammals was taken. The equation of the least-squares
line for the relationship between brain mass and body
mass is computed as
Based on the residual plot, is a linear model appropriate
for describing the relationship between brain mass and
body mass?
body mass = 561.9(brain mass) - 16485.
O Alinear model is not appropriate, because the
residuals are not centered about zero.
O Alinear model is appropriate, because there is a clear
pattern shown in the residual plot.
O Alinear model is not appropriate, because there is a
clear pattern shown in the residual plot.
O Alinear model is appropriate, because many of the
residuals are close to zero for all brain weights.
