Answer 2

Answer:

The answer is a paired-samples t-test.

Explanation:

The paired sample t-test refers to a statistical procedure that is utilized to establish if the principal difference between the two observations is zero. In a paired sample t-test, each subject must be measured twice. This is the reason why there are pairs of observations.

Common applications that are usually utilized in the paired sample t-test are case-control studies or repeated-measures designs. The paired sample t-test also includes two hypotheses, the null hypothesis, and the alternative hypothesis.
