Question

Can someone please help me with this?

Answer 1

Answer: Option (2)

Step-by-step explanation:

When x=10,

• The median-median line gives $y=1.4(10)+2.6=16.6$.
• The least-squares regression line gives $y=0.9(10)+4.2=13.2$.

13.2 is closer to 14 than 16.6, so the least-squares regression line is a better prediction.
