Question

Assume that you want to use a 0.01 significance level to test the cliam that the mean pulse rate of women is grater than the mean pulse rate of men using the sample data set in Appendix B. Both samples have 40 values. If we use df=smaller of n1-1 and n2-1, we get df = 39, and the corresponding critical value is t=2.426. If we calculate df using Formula 9-1, we get df= 77.2, and the corresponding critical value is 2,376. How is using critical value of t= 2.426 more conservative than using the critical value of 2.376.
