Answer

Explanation:

Step1: Analyze first statement

Let pairs of shoes = 0. Substitute into regression line. Predicted Hats = 4 + 0.2(0) = 4.

Step2: Analyze second statement

Let pairs of shoes = 8. Substitute into regression line. Predicted Hats = 4+0.2(8)=4 + 1.6=5.6, not 20.

Answer:

Jen predicts that a person who does not own any shoes will own 4 hats.
