There's a roughly linear relationship between the length of someone's femur (the long leg-bone in your thigh) and their expected height. Within a certain population, this relationship can be expressed using the formula h=63.8+2.39fh=63.8+2.39f, where hh represents the expected height in centimeters and ff represents the length of the femur in centimeters. What is the meaning of the ff-value when h=169h=169?
A:The femur length for someone with an expected height of 169 centimeters.
B:The change in expected height for every one additional centimeter of femur length.
C:The expected height for someone with a femur length of 169 centimeters.
D:The femur length for someone with an expected height of 44 centimeters.
