for a two sample hypothesis test, we always have a two tail test.
true
false

Explanation:

In two - sample hypothesis tests, we can have one - tailed tests (e.g., testing if the mean of population 1 is greater than the mean of population 2) or two - tailed tests (testing if the means are different). The statement "we always have a two - tail test" is incorrect.

Answer:

False
