We are taking alternative and null hypothesis t- test
In null hypothesis we see that population of two unrelated groups are equal

if we reject the hypothesis and accept the alternative hypothesis than population means
H₁: u1 ≠ u2
In this test we need a significance level that is also called alpha level who reject or accept the null hypothesis.
