When testing for the difference between the means of two normal populations using two independent samples with equal variances and with sizes of n_x = 20 and n_y = 15,what is the number of degrees of freedom for the t test statistic? A)35 B)33 C)18 D)13

Question

Quizplus · Accepted Answer

The degrees of freedom for the t test statistic in this scenario can be calculated as follows:

df = (n1 - 1) + (n2 - 1)
df = (20 - 1) + (15 - 1)
df = 33

Therefore, the correct answer is B) 33.
