Textbook Question
Chapter 9.2, Problem 4BSC
Degrees of Freedom For Example 1 on page 431, we used df = smaller of n1 − 1 and n2 − 1, we got df = 11, and the corresponding critical values are t = ± 2.201. If we calculate df using Formula 9-1, 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?
