To test if two population means are the same.

Explanation:

To Find :What is the purpose of a two sample t-test?

Solution:

Two sample test is used to check the difference between the two population means .

Let us suppose mean of population 1 =
`\mu_1`

Let us suppose mean of population 2=
`\mu_2`

So, Two sample test is used to check whether
`\mu_1=\mu_2` or
`\mu _1\\eq\mu_2`

Hence the purpose of a two sample t-test is To test if two population means are the same.
