Heights of Parents and Children Refer to Data Set 2 in Appendix B.

a. Find the regression equation that expresses the dependent variable of a child’s height in terms of the independent variable of the height of the mother.

b. Find the regression equation that expresses the dependent variable of a child’s height in terms of the independent variable of the height of the father.

c. Find the regression equation that expresses the dependent variable of a child’s height in terms of the independent variables of the height of the mother and the height of the father.

d. For the regression equations found in parts (a), (b), and (c), which is the best equation for predicting the height of a child? Why?

e. Is the best regression equation identified in part

(d) a good equation for predicting a child’s height? Why or why not?
