Given the following information,calculate the degrees of freedom that should be used in the pooled-standard deviation t-test. 
A)df = 41 
B)df = 39 
C)df = 16 
D)df = 25

Quizplus · Accepted Answer

The degrees of freedom for a pooled-standard deviation t-test are calculated using the formula (n1 - 1) + (n2 - 1), where n1 and n2 are the sample sizes of the two groups being compared. Without information about the sample sizes, we cannot determine the exact degrees of freedom. However, since the answer choices range from 16 to 41, we can assume that the sample sizes are relatively small. Based on this assumption, the best choice is option B, which has the smallest value of 39.
