Answer: a) urban areas
Explanation:
The reason for these migrations was not the imminent threat of war, the natural catastrophe and fear of famine, as is the case with immigration. The goal is the primarily unfortunate economic situation, racial segregation, and discrimination. Better living conditions have forced a vast population to migrate. During the twentieth century, two significant waves of migration occurred. One in the period from 1910 to 1940 and the other after the end of World War II until 1970.
What we are looking for is the confidence interval.
Given:
Sample it is denoted by n = 10
Mean = 80
Standard deviation = 12
Confidence Interval = 99%
Now compute for the margin of error, the formula is Za/2 * σ/√(n)
A 99% level of confidence has a critical value of zα/2 = 2.58.
The standard error is σ/√(n) = 3.162
Multiply 2.58 by 3.162 = 9.8 is the margin of error.
The formula for confidence interval is x̅ ± Za/2 * σ/√(n)
= 80 ± 9.8
= 70.2 < x< 89.8
