In a regression analysis of a first-order model involving 3 predictor variables and 25 observations, the following estimated regression equation was developed. = 12 - 18x₁ + 4x₂ + 15x₃ Also, the following standard errors and the sum of squares were obtained.
S_b₁ = 3
S_b₂ = 6
S_b₃ = 7
SST = 4900
SSE = 1296

If you want to determine whether or not the coefficients of the independent variables are significant, the critical t value at α = .01 is
