Answer
SSE = 22.268
$s^{2} = 5.567$
Std, Error of Estimate = 2.35944
Work Step by Step
From the printout, we observe that SSE = 22.268 (value of sum of squares corresponding to the residual).
Variance is 5.567 (Mean square column corresponding to residual row)
Standard error of estimate is given in column std. error of estimate, which is 2.35944
