Statistics II multiple regression equation question

In a multiple regression equation, two independent variables are considered, and the sample size is 25. The regression coefficients and the standard errors are as follows.

b1 = 2.676   Sb1 = 0.56
b2 = -0.880   Sb2 = 0.71
 
Conduct a test of hypothesis to determine whether either independent variable has a coefficient equal to zero. Would you consider deleting either variable from the regression equation? Use the .05 significance level. (Negative amounts should be indicated by a minus sign. Round your answers to 3 decimal places.)
 
H0: b1 = 0   H0: b2 = 0
H1: b1 ≠ 0   H1: b2 ≠ 0
H0 is rejected if t < -2.074 or t > 2.074
 
 t= _____,  t=_____
