Answer:
The migration of the African-Americans to Harlem in the USA empowered the African-Americans in the society in the early 1900s. This was one of the greatest accomplishments of the African-Americans in history.
Explanation:
The "Harlem Renaissance" was originally called the "New Negro Movement." During the "Reconstruction Era," many of the African Americans felt a newfound empowerment in the society. They started leaving the South, where most of them were enslaved and maltreated. Many of them moved to other places such as "Harlem" in New York City. It became an ideal destination for many "Negros" and their number increased over time.<u> This then became an African-American neighborhood</u>.
African-Americans started producing plays with actors of their descent. Several Negro poets emerged describing the life of the African-Americans. Negros became more literate and able when it comes to expressing themselves in the society. They even had their own newspaper known as<em> "The New Negro Movement."</em>
Answer:
90% confidence interval for the population mean is between a lower limit of $92.18 and an upper limit of $107.82.
Step-by-step explanation:
Confidence interval for a population mean is given as mean +/- margin of error (E)
mean = $100
sd = $25.20
n = 30
degree of freedom = n-1 = 30-1 = 29
confidence level (C) = 90% = 0.9
significance level = 1 - C = 1 - 0.9 = 0.1 = 10%
critical value (t) corresponding to 29 degrees of freedom and 10% significance level is 1.699
E = t×sd/√n = 1.699×25.20/√30 = $7.82
Lower limit of population mean = mean - E = 100 - 7.82 = $92.18
Upper limit of population mean = mean + E = 100 + 7.82 = $107.82
90% confidence interval is ($92.18, $107.82)
The continent which has 59% of the total population will have more than 5.31 billion people by 2050.
<u>Step-by-step explanation:</u>
It is given that,
- The total number of people is 9 billion.
- The estimated number of people in 2050 year is 5.31 billion.
Therefore, you need to find out which continent has the estimated number by finding the percentage value.
<u>To find what percent 5.31 is of billion is of 9 billion :</u>
Let x be the percentage to be calculated.
⇒ x percent of 9 billion is 5.31 billion.
⇒ (x/100) × 9 = 5.31
⇒ x = (5.31 × 100) / 9
⇒ x = 531 / 9
⇒ x = 59 %
∴ The continent which has 59% of the total population will have more than 5.31 billion people by 2050.
