Question

Predict the vital capacity of a 20-year-old 5'5" female who weighs 120 pounds using the equation below: vc = (0.041) h - (0.018) a - 2.69

Answer 1

The corresponding height in inches is 
     h=65 inches

The vital capacity is 
     $vc=\left(0.041\right)\left(65\right)-0.018\left(120\right)-2.69=-2.185$

The vital capacity is -2.185.
