The following estimated regression equation was developed relating yearly income (y in $1000s) of 30 individuals with their age (x1) and their gender (x2) (0 if male and 1 if female). ŷ = 30 + .7x1 + 3x2 also provided are sst = 1200 and sse = 384. if we want to test for the significance of the model, the critical value of f at α = .05 is:
