Anthropologists use a linear model that relates femur length (cm) to height (cm). The model allows an anthropologist to determine the height of an individual when only a partial skeleton (including the femur) is found. The samples used to create the model ranged from a femur length of 38cm to a femur length of 51 cm. The data yielded the following LSRL:

stack H e i g h t with hat on top equals 80.681 plus 1.923 left parenthesis f e m u r space l e n g t h right parenthesis

Part 1: (4 pts)

Give the slope (2 pts) and interpret what it means in the context of the question (2 pts).

Part 2: (4 pts)

Give the y-intercept (2 pts) and interpret what it means in the context of the question (2 pts).

Part 3: (6 pts)

Use the model to predict the height of a man with a femur length of 54 cm (4 pts), then comment on the usefulness of your solution (2 pts).
