In Figure 11.20:

(a) predictor and outcome are independent random variables;

(b) the correlation between predictor and outcome is close to zero;

(c) outcome increases as predictor increases;

(d) predictor and outcome are linearly related;

(e) the relationship could be made linear by a logarithmic transformation of the outcome.
