Given that the difference surpasses the threshold level it means the experiment is highly significant according to statistics a p-value less than 0.05 (p ≤ 0.05) is statistically significant.

Therefore, we reject the null hypothesis, and accept the alternative hypothesis as the correct hypothesis
Answer: The position of the multi-million African American population has changed.
Explanation:
Throughout a long part of American history, the African-American population was in a subordinate position, especially in the south of the country where they did slave hard labor and had no rights. That was one of the factors that led to the civil war. Abraham Lincoln proposed adopting amendments that were supposed to solve the problem after the war and bring freedom to African Americans. Lincoln did not experience that historic moment because he was assassinated. Nevertheless, his policy was continued by A. Johnson. In such circumstances, the thirteenth amendment to the United States Constitution was passed, where countries were forced to abide by abolishing slavery. The situation did not improve "overnight," and this was only the beginning of the fight against slavery, given that many states did not immediately implement the law in practice, especially in some parts of the south of the country.
