Predicting Height Use the foot lengths and heights from the 19 males in Data Set 7 “Foot and Height.” Find the best predicted height of a male who has a foot length of 28 cm. 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.
