Question

Solve the math problem

Answer 1

Answer:

Explanatory variable (independent variable)

• The variable that affects the other variable.
• Drawn along the horizontal axis.

Response variable (dependent variable)

• The variable that is being affected.  
• Drawn up the vertical axis.

(a) As the class wondered if they could predict the father's height, when they know the son's height

Explanatory variable = son's height

Response variable = father's height

(even though this is contrary to real-life, where the father's height would be used to predict the son's height)

(b) **see first attachment**

(c)  The association is positive since the father's height increases as the son's height increases.

(d)  **see second attachment**

Outlier = Paul  (64.5, 73)

This point is far away from the majority of points on the scatter plot.

If we add a regression line to the scatter plot, we can see that this data point is the farthest from the regression line.
