Question

There's a roughly linear relationship between the length of someone's femur (the long

Answer 1

For the linear relationship between the length of someone's femur (the long leg-bone in your thigh) and their expected height expressed as h = 2.35f + 54.7, the meaning of the f-value when h = 149 is the first option: The femur length for someone with an expected height of 149 centimeters.        

The linear relationship between the length of someone's femur and their expected height is:

$h = 2.35f + 54.7$     (1)                      

Where:

h: is the height in centimeters

f: is the length of the femur in centimeters

When h is 149, the f-value is:

$f = \frac{h - 54.7}{2.35} = \frac{149 - 54.7}{2.35} = 40.1 cm$

Hence, the length of someone's femur that has a height of 149 cm is 40.1 cm.

Therefore, the correct option is the first: The femur length for someone with an expected height of 149 centimeters.
