Question

when conducting a t - test with 23 people in one group and 25 people in another group, the degrees of freedom are
48
47
46
45

Explanation:

Step1: Recall the formula for degrees of freedom in a two - sample t - test

For a two - sample t - test with sample sizes \(n_1\) and \(n_2\), the degrees of freedom \(df=n_1 + n_2-2\).

Step2: Substitute the given values

Here, \(n_1 = 23\) and \(n_2=25\). Then \(df=23 + 25-2\).
