Question

Quizplus · Accepted Answer

The degrees of freedom for a t-test comparing two independent samples of size 10 would be 18 only if the pooled variance estimate is used. However, it is not specified in the given statement whether the pooled variance estimate is used or not. Therefore, we cannot determine the degrees of freedom for the t-test from the given information, and the statement is false.
