In a simple linear regression analysis with n=22n = 22n=22 points, the total sum of squares is textSST=250.0\\text{SST} = 250.0textSST=250.0 and the coefficient of determination is R2=0.84R^2 = 0.84R2=0.84. Calculate the standard error of the regression (se=sqrtfractextSSEn−2s_e = \\sqrt{\\frac{\\text{SSE}}{n-2}}se​=sqrtfractextSSEn−2).
