Textbook Question
Chapter 3, Problem 3.19E
A regression equation for y = handspan (cm) and x =height (inches) was discussed in Section 3.2. If the roles of the variables are reversed and only women are considered, the regression equation is
Average height = 51.1 ÷ 0.7 (Handspan).
- Interpret the slope of 0.7 in terms of how height changes as handspan increases.
- What is the estimated average height of women with a handspan of 20 cm?
- Molly has a handspan of 20 cm and is 66.5 inches tall. What is the prediction error (residual) for Molly?
