Two samples are drawn from two normal types of population. Which of the following test statistics can be used to show that the two types of population have the same mean while both have the same variance?

To determine whether two samples drawn from normal populations have the same mean while having the same variance, the Two sample pooled t-test is appropriate. The pooled t-test assumes equal variances and is used to compare the means of two independent samples from normal populations.
I am confused!
