Answer:

Step-by-step explanation:
To find the unemployment rate we have the next expression:

We have the next data:
200 million employed
20 million unemployed
40 million umemployed are not looking for a job
Then the total labor force will be the employed and the unemployed population then de have 260 million

Answer:
The expected participation rate is 0.637.
The standard error is 0.04397
Step-by-step explanation:
For each working age people asked, there are only two possible outcomes. Either they are in the labor force, or they are not. This means that we can solve this problem using binomial distribution probability concepts.
Binomial probability:
Expected value for the participation rate: The expected value is the probability of a success. In this problem, a success is a working age people being in the labor force. 63.7% of them are. So
. This means that the expected participation rate is 0.637.
Standard error for the participation rate:
The standard error is given by the following formula:
.
In this problem, 120 people are asked, so 
.
So the standard error is 0.04397
Answer:
Free press is essential since the government does not control the press.
Step-by-step explanation:
For example, the Untied States has free press so authors can spread information (whether for good or evil) while other countries like China control their press and access to press outside of their country, making it much harder for citizens to see the world from another perspective rather than what the government is willing to tell them.
Since the United States is a democracy, it is important to allow their citizens to have the right to speech and the press if people want to form opinions of their own.
Answer:
Step-by-step explanation:
probability ∈[0,1]
or probability ≥0
and ≤1
so a,b,g cannot be the probability of an event.
