In a study of the lung
- a. Predict the FEV1 for a boy who is 1.4 m tall, if the measurement was taken at a pressure of 730 mm and last year’s measurement was 2.113 L.
- b. If two girls differ in height by 5 cm, by how much would you expect their FEV1 measurements to differ, other things being equal?
- c. The constant term β0 is estimated to be negative. But FEV1 must always be positive. Is something wrong? Explain.
