Anthropologists often try to reconstruct information using partial human remains at burial sites. For instance, after finding a femur (thighbone), they may want to predict how tall an individual was. An equation they use to do this is ˆy = 61.4 + 2.4x, where ˆy is the predicted height and x is the length of the femur, both in centimeters.

(a) Identify the y-intercept and slope of the equation. Interpret the slope.

(b) A femur found at a particular site has length of 50 cm.

What is the predicted height of the person who had that femur?
