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 = 2.36 f + 55.4 h=2.36f+55.4, where h h represents the expected height in centimeters and f f represents the length of the femur in centimeters. what could the number 2.36 represent in the equation?
