Solution

The two-sample t-test is one of the most frequently used hypothesis tests in real world. It is useful to evaluate whether the average (mean) difference between two groups is really significant or if it is due to random error or chance. It also helps to give answers to questions like whether the average success rate is higher after the execution of a new sales technique or whether the test results of patients who received a drug are better than of those who received a placebo treatment.
