Repeat Exercise 18 using the foot lengths and heights of the 19 males from Data Set 2 “Foot and Height.”

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.

Exercise 18:

Use the foot lengths and heights to find the best predicted height of a male who has a foot length of 28 cm. Would the result be helpful to police crime scene investigators in trying to describe the male?

Data Set 2: Foot and Height 

Foot and height measurements are from 40 subjects (first five rows shown here). SEX is gender of subject, AGE is age in years, FOOT LENGTH is length of foot (cm), SHOE PRINT is length of shoe (cm), SHOE SIZE is reported shoe size, and HEIGHT is height (cm) of the subject.
