Explanation:
Lower class can not usually afford store like this. Hence why they are called lower class
a) ( 0.8509718, 0.8890282)
b) ( 0.7255, 0.7745)
Explanation:
(a)
Given that , a = 0.05, Z(0.025) =1.96 (from standard normal table)
So Margin of error = Z × sqrt(p × (1-p)/n) = 1.96 × sqrt(0.87 × (1-0.87) / 1200)
=0.01902816
So 95 % confidence interval is
p+/-E
0.87+/-0.01902816
( 0.8509718, 0.8890282)
(b)
Margin of error = 1.96 × sqrt (0.75 × (1-0.75) / 1200) = 0.0245
So 95% confidence interval is
p+/-E
0.75+/-0.0245
( 0.7255, 0.7745)

Answer:
The correct answer is Middle.
Explanation:
Traditionally, the middle class is considered as the largest representative of the population in developed countries, although it is also a reality that the limits of this class are not very strong, since it can range from professionals and administrators of important level to employees in the area of services. So, as a consequence of this lack of internal union, it is often subdivided into upper middle class and lower middle class.
