If t Stat is larger than the critical two-tail value, we reject Ho. In this case, t Stat is -1.956808 whereas t Critical two-tail is 1.9656147. t Stat is smaller than t Critical value, therefore, Ho will not be rejected. Therefore, the data support Ho meaning that the number of months employed can be considered equal for applicants with low credit risk as for those with high credit risk evaluations.
