Answer:
Suppose a senator considers introducing a bill to legislate a minimum hourly wage of $12.50.
Wage Labor Demanded Labor Supplied
$12.50 375,000 625,000
This will result in a surplus of labor (625,000 higher than 375,000)
Which of the following statements are true?
- Binding minimum wages cause structural unemployment. As with all price floors, a deadweight loss results, because the quantity supplied is much greater than the quantity demanded. In this case, the price of labor is the wage, and the deadweight loss = structural unemployment
- In the absence of price controls, a surplus puts downward pressure on wages until they fall to the equilibrium. Since a labor surplus exists, the price of labor should start to decrease in order to match the equilibrium price.
- If the minimum wage is set at $12.50, the market will not reach equilibrium. The quantity supplied of labor is much greater than the quantity demanded for labor resulting in a surplus.
The closest to the minimum number of consumers needed to obtain the estimate with the desired precision is (b) 271
Explanation:
When the prior estimate of population proportion is not given , then the formula to find the sample size is given by :-
where E = Margin of error.
z* = Critical z-value.
As per given , we have
E = 5%=0.05
Confidence level = 90%
The critical value of z at 90% is 1.645 (By z-table)
Put all values in the formula , we get
n=0.25(1.645/0.05)²
n=0.25(32.9)²
n=270.6025≈271
Thus, the minimum sample size needed = 271
Hence , the correct answer is 271 .
