Chapter 8.1, Problem 7E

a.

To determine

Find the predicted ${\text{FEV}}_1$ of a boy with 1.4 meter height, measured at 730 mm pressure and with 2.113L last year’s measurement.

b.

To determine

Find the difference between the ${\text{FEV}}_1$ of two girls when their height differ by 5 cm with equal measurement in all other variables.

c.

To determine

Explain whether the given claim “The constant term ${\beta }_0$ is estimated to be negative, but ${\text{FEV}}_1$ must always be positive” is wrong.
