Because for the 2-sided test (0.05: 2 = 2.5%) it can be seen that the value of T-table = 2.032. T-count = 2.875 can be seen from the column Equal variances assusmed (homogeneous), it can be seen that the value of Tcount = 2.875. So it can be seen that Tcount > Ttable was 2.875 > 2.032 with a significance was 0.007 < 0.05.
