It might be independent t-test.
Step-by-step explanation:
Basically it is a independent t- test .Independent sample test t - test or student test is a statistical test.In this test we determine that there is a statistically significant difference between the mean when we are talking about unrelated group.
We are taking alternative and null hypothesis t- test
In null hypothesis we see that population of two unrelated groups are equal
H₀: u1 = u2
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.
