Answer:

0.3.

Explanation:

The residual of a data point is equal to the observed value minus the predicted value. (Stat Trek)

What's the predicted y-value of a point with
x = 5 based on this best-fit regression line?


y = -0.2* 5 + 1.7 = 0.7.

The observed value here is
y = 1. As a result, the residual for this point is
1 - 0.7 = 0.3.
