Anthropologists often try to reconstruct information using partial human remains at burial sites. For instance, after finding a femur, they may want to predict how tall an individual was. An equation they use to do this is y=61.4+2.4x, where y is 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 50cm. What is the predicted height of the person who had that femur?
