Given the following information, calculate the degrees of freedom that should be used in the pooled-variance t test.
$$\begin{array} { l l }
s _ { 1 } ^ { 2 } = 4 & s _ { 2 } ^ { 2 } = 6 \
n _ { 1 } = 16 & n _ { 2 } = 25
\end{array}$$
A) df = 39
B) df = 41
C) df = 16
D) df = 25

Quizplus · Accepted Answer

The degrees of freedom for the pooled-variance t test is calculated as:df = (n1 - 1) + (n2 - 1) = 15 + 24 = 39
