In Example 2.19 on page 79 we computed z-scores for patient #772 in the ICU Admissions dataset, who had a high systolic blood pressure reading of 204 but a low pulse rate of 52 bpm.
(a) Find the point corresponding to patient #772 on the scatterplot of blood pressure vs heart rate shown inFigure 2.61.

(b) Patient #772 has a high blood pressure reading but a low pulse rate. Does the scatterplot in Figure 2.61 support a conjecture that these two variables have a negative association?
