Question
In a two variable linear regression model, four X and Y
values were given and value of F statistic needs to be calculated. Regression equation of X on Y is given as X = 2 + 0.7 Y.Solution
X = 2 + 0.7 Y F = (ESS/df) / (RSS/df) N = 4 RSS (df) = 4 β 2 = 2 ESS (df) = 2-1 = 1 R2 = ESS/TSS 
Β ESS = (bxy)2 Β = 0.7*0.7*20 = 9.8 TSS = Β = 30 R2 = ESS/TSS = 9.8/30 = 0.33 F = (0.33/1) / (0.67/2) = 0.98
