Answer:
Plessy v. Ferguson
Explanation:
The Plessy v. Ferguson case happened in 1896. The decision from this case effectively started the Racial Segregation in United States. During the segregation, the government separated the public infrastructures into two: Those who can be used by white citizens only and those who can be used by black citizens only. This infrastructures cover all facilities ranging from Schools, Public Transportation, public bathrooms, etc.
But, the facilities provided for the Black citizens tend to be lower in quality compared to the facilities provided for white citizens. This led to a deeper problem for the Black community. For example, Due to the low quality of schools for black citizens, they produce a generation of graduates who has lesser chance to obtain high paying jobs. This prevented the black community to advance in society.
Answer:
B) There is not sufficient evidence to support the claim that the true proportion is less than 21 percent.
Explanation:
According to a different source, these are the options that come with this question:
A) There is sufficient evidence to support the claim that the true proportion is less than 21percent.
B) There is not sufficient evidence to support the claim that the true proportion is less than 21percent.
C) There is sufficient evidence to support the claim that the true proportion is greater than 21percent.
D) There is not sufficient evidence to support the claim that the true proportion is greater than 21percent.
This would be the best way to explain what this conclusion means. The hypothesis states that more than 21% of the population suffers from professional problems due to extreme shyness. Moreover, the null hypothesis states that there is no meaningful relationship between two measured phenomena. If we "fail to reject" the hypothesis, this means that we do not have evidence that shows that the hypothesis is not true. Therefore, we can claim that there is not sufficient evidence to support the claim that the true proportion is less than 21 percent.
