Suppose two samples of sizes 25 and 35, respectively, are independently drawn from two populations that are both normally distributed.Also assume the population variances are unknown but equal.What is the number of degrees of freedom that the t test statistic would have?
A) 34
B) 58
C) 59
D) 60

The degrees of freedom for a t-test with two independent samples with equal variances is calculated as (n1 + n2 - 2), where n1 and n2 are the sample sizes. So, 25 + 35 - 2 = 58.
