Exhibit 16-1
In a regression analysis involving 25 observations, the following estimated regression equation was developed.

Y=10 - 18X1+ 3X2 + 14X3

Also, the following standard errors and the sum of squares were obtained.

Sb1 = 3 Sb2 = 6 Sb3 = 7
SST = 4,800 SSE = 1,296



Refer to Exhibit 16-1. If you want to determine whether or not the coefficients of the independent variables are significant, the critical value of t statistic at α = 0.05 is
