• #### Unit 3 Discussion: Using Regression Models – Locked

11:59 PM
In Unit 3, we are investigating regression models. In this discussion you will use a regression equation to make a prediction. For this discussion, you will post at least twice – 1) an initial post, and then 2) a reply to a classmate.Archeologists have developed formulas to predict the height, and in some cases, the age at death of the deceased by knowing the lengths of certain bones in the body. The long bones of the body grow at approximately the same rate. Thus, a linear relationship exists between the length of the bones and the personâ€™s height. If the length of one of these major bones â€“ the femur (F), the tibia (T), the humerus (H), or the radius (R) â€“ is known, the height,
h, of a person can be calculated using one of the following formulas. The relationship between bone length and height is different for males and females.
Male
h = 2.24F + 69.09

h = 2.39T + 81.68

h = 2.97H + 73.57

h = 3.65R + 80.41
Female
h = 2.23F + 61.41

h = 2.53T + 72.57

h = 3.14H + 64.98

h = 3.88R + 73.51
