Question

The scatter plot and line of best fit below show the length of 7 people's femur (the
long leg bone in the thigh) and their height in centimeters. What is the meaning of
the y-value on the line when x = 40?

Answer 1

Answer:

An expected height of 160.6 centimeters when the femur has a length of 40 centimeters.

Step-by-step explanation:

The line of best fit makes a prediction. In other words, it tells us what height to expect for any given femur length.

x represents femur length and y represents height, so the y-value on the line when x=40x is the expected height when the femur length is 40 cm.

Answer 2

Using the Regression model given, the meaning of the expression is " the expected height of the individual with a femur length of 40 would be about 160 cm

• The regression model compares the relationship between the independent and dependent variable. Here, Femur length and height

• The height of the individual with a femur length of 40 cm would be about 160cm.

Hence, the expected height of the individual with a femur length of 40 would be about 160 cm.
