Find the residual value that would need to be plotted if the y-value is 195 and the ŷ is 192.

Answer 1

The residual value is calculated as the difference between the observed value (\(y\)) and the predicted value (\(ŷ\)). In this case, the observed value is 195 and the predicted value is 192.

The formula for the residual (\(r\)) is:

\[ r = y - ŷ \]

Plugging in the given values:

\[ r = 195 - 192 = 3 \]

So, the residual value that needs to be plotted is 3.
