Use the below data to answer the questions. Estimate the standard error of the residuals about the regression line.
The standard error is given by the square root of the sum of squared differences between actual
and predicted y values divided by n - 2. Thus, we know that:
sigma{i=1 to n} (yi - ymean)2 = (12 - 26.75)2 … = 6423.75.
So that the standard error is
Standard error = sqrt( 6423.75 / (20 - 2)) = 18.891
