E - Standard error of b1

31. The commercial division of a real estate firm is conducting a regression analysis of the relationship between gross rents CX) and selling price (Y) for apartment building. Data have been collected on several properties recently sold, and the following output has been obtained in computer run ANOVA df SS 0.798 Regressior 18.878 Residual Total 19.676 Coefficients Standard Error t Stat 1.954 1.068 Intercept 1.830 X Variable 0.053 0.092 0.582

Explanation / Answer

a_)regression coefficients of bo =1.954

regression coefficients of b1=0.053

b|)Variance of the regression =(SSE/(n-2))=18.878/8=2.3598

c)Standard error of the regression =(2.3598)1/2 =1.5361

d) Estimated variance of b1 =(0.092)2 =0.0085

e)Standard error of b1 =(1.830)2 =3.3489
