Degrees of Freedom For Example 1 on page 431, we used df = smaller of n1 —I and n2—1, we got df = 11, and the corresponding critical values are it = ± 2.201. If we calculate df using Formula9-1, we get df = 19.063, and the corresponding critical values are ± 2.093. How is using the critical values of t = ± 2.201 more "conservative" than using the critical values of ± 2.093?
