Question

The data can be modeled by the regression line y=-1.2x+9.2. What is the residual at x=5 ?

x 1 3 3 4 5 6
y 9 5 7 3 4 2

Answer 1

The residual at x=5 is 3.2.

Step-by-step explanation:

To find the residual at x=5, we can substitute x=5 into the regression equation y=-1.2x+9.2:

y = -1.2(5) + 9.2

y = -6 + 9.2

y = 3.2

So, the residual at x=5 is 3.2.
