Use the Body Fat data set with the response variable Density to answer the following questions.

(a) Create and summarize scatterplots of Density versus each of the explanatory variables Abdomen, Hip, and Ankle.

(b) Compute the sample correlation coefficient associated with each of the scatterplots in part (a).

(c) Identify any pattern or bivariate outliers in the scatterplots in part (a).

(d) Determine which of the explanatory variables Abdomen, Hip, and Ankle appears to have the strongest linear relationship with Density.

(e) Fit the least squares regression line for Density with the explanatory variable having the strongest linear relationship with Density identified in part (d).
