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 77.7 centimeters. an expected height of 77.7 centimeters when the femur has a length of 150 centimeters. an expected height of 150 centimeters when the femur has a length of 77.7 centimeters. the height of an actual person with a femur length of 77.7 centimeters is 150 centimeters.

Explanation:

Step1: Identify the variables

The x - variable is femur length and y - variable is height.

Step2: Find the x - value for y = 150

We need to find the femur length (x - value) when the height (y - value) is 150 cm by looking at the line of best - fit on the scatter - plot.

Answer:

We would estimate the x - value (femur length) on the line of best - fit when y = 150 by visually inspecting the scatter - plot. Without the actual scatter - plot values or equation of the line of best - fit, we can't give a numerical answer. But the process is to find the point on the line of best - fit where the y - coordinate is 150 and then read the corresponding x - coordinate.
