Question

question the scatter plot and line of best fit below show the length of 11 peoples femur (the long leg bone in the thigh) and their height in centimeters. what is the meaning of the x - value on the line when y = 150? answer the height of an actual person with a femur length of 150 centimeters is 37.7 centimeters. an expected height of 37.7 centimeters when the femur has a length of 150 centimeters. an expected height of 150 centimeters when the femur has a length of 37.7 centimeters. the height of an actual person with a femur length of 37.7 centimeters is 150 centimeters.

Explanation:

In the scatter - plot, $x$ represents femur length and $y$ represents height. When $y = 150$ (height is 150 cm), the $x$ - value on the line of best fit gives the expected femur length for a person with that height. Looking at the options, when $y = 150$, the $x$ - value (femur length) is approximately 37.7 cm. This means an expected height of 150 centimeters when the femur has a length of 37.7 centimeters.

Answer:

An expected height of 150 centimeters when the femur has a length of 37.7 centimeters.
