Answer 1

Answer:

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.
