Pulse Rate and Blood Pressure Use all of the pulse rates and systolic blood pressure amounts for adult females in Data Set 1 “Body Data” in Appendix B. If a subject has a pulse rate of 80 beats per minute, what is the best predicted systolic blood pressure? Large Data Sets. Exercises 25–32 use the same Appendix B data sets as Exercises 25–32 in Section 10-1. In each case, find the regression equation, letting the first variable be the predictor (x) variable. Find the indicated predicted values following the prediction procedure summarized in Figure 10-5 on page 466.
