If the predicted value when x=11 is hat (y)=37.6 and the actual value at x=11 is measured to be y=38.3 . find the value of the residual at this point.

To find the value of the residual at this point, we need to calculate the difference between the actual value and the predicted value.<br /><br />The residual is defined as the difference between the actual value and the predicted value. It is calculated as:<br /><br />Residual = Actual value - Predicted value<br /><br />In this case, the actual value at x=11 is y=38.3 and the predicted value at x=11 is $\hat{y}=37.6$.<br /><br />So:<br /><br />Residual = 3 - 37.6 = 0.7<br /><br />Therefore, the value of the residual at this point is 0.7.
