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

Answer:
The US income will be $12,201 and South Korea's income will be $21,911. US income will grow by multiple of 1.2 while South Korea's GDP will grow by multiples of 2.19.
Explanation:
Initial income of both the countries is $10,000.
Growth rate of South Korea is 4%.
Growth rate of US is 1%.
In 20 years, South Korea's income will be,
=Initial income*
=$10,000*
=$10,000*2.1911
=$21,911
Similarly, we can find US income.
=Initial income*
=$10,000*
=$10,000*1.2201
=$12,201
So, South Korea's income is $21,911 while US's income is $12,201.
South Korea's income grows by the multiples of 2.1911. While, US's income grows by the multiples of 1.2201
