Answer:
a) unemployment rate = 15
b) unemployment rate = 2.5
Explanation:
unemployed people are those who are willing and available to work and have actively been seeking a job in the past four weeks. This accurately describes the 12 people who are willing, able and looking for work but cannot find jobs. To calculate the unemployment rate in percentage, the following formula is used:
Where:
a) Number of unemployed = 12
Labour force = 80 (number of people over 16 years of age)
b) if 10 of the unemployed people get discouraged and give up looking for work, the number of unemployed becomes 2 persons, (12 - 10 = 2).

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)
