Using the Body Fat data set,

(a) Fit a simple linear regression model for relating body density (????) to chest circumference (????).

(b) Use the residuals to check the regression assumptions.

(c) Provided the regression assumptions appear to be satisfied, test whether or not there is a linear relationship between body density and chest circumference.

(d) Determine the percentage of the total variation in body density explained by the simple linear regression model.

(e) Does this model appear to do a good job explaining body density? Explain.
