Question

question
the scatter plot and line of best fit below show the length of 5 people’s femur (the long leg bone in the thigh) and their height in centimeters. what does the point (37, 149.7) represent?
answer
the height of an actual person with a femur length of 149.7 centimeters is 37 centimeters.
the height of an actual person with a femur length of 37 centimeters is 149.7 centimeters.
an expected height of 37 centimeters when the femur has a length of 149.7 centimeters.
an expected height of 149.7 centimeters when the femur has a length of 37 centimeters.

Explanation:

In a scatter plot with femur length (x - axis) and height (y - axis), the point \((37,149.7)\) has \(x = 37\) (femur length in cm) and \(y=149.7\) (height in cm). The line of best fit gives the expected height for a given femur length. So, it represents an expected height of 149.7 centimeters when the femur has a length of 37 centimeters. The other options misinterpret the axes: the first two talk about "actual" (but the line of best fit is for expected, not actual in the sense of a single point on the line) and the third swaps the x and y values.

Answer:

An expected height of 149.7 centimeters when the femur has a length of 37 centimeters.
