  1. The degrees of freedom are 4 plus 3 minus 2, which is 5. Alternatively, we can
  2. just add the degrees of freedom of each. 3 plus 2, and then we find that our
  3. t-critical value is positive and negative 2.571. This t-statistic, -1.34, is
  4. not in the critical region defined by these critical values. Therefore we'll
  5. accept the null.
