Quizplus · Accepted Answer

The degrees of freedom for a t-test with independent samples is calculated as (n1 + n2 - 2), where n1 is the sample size of the experimental group and n2 is the sample size of the control group. Therefore, the degrees of freedom in this scenario would be (50 + 40 - 2) = 88. Therefore, the correct answer is B.
