Researchers in the health and social sciences can obtain their data by getting it directly from the subjects they’re interested in. This data they collect is called primary data. Another type of data that may help researchers is the data that has already been gathered by someone else. This is called secondary data. Hope this helped!
Answer:
These statements are true:
A) The Federal Reserve does not set the Federal funds rate, but it influences it through the use of open market operations:
For example, at the very moment the Fed funds rate is 1.75%. If the Fed wanted to raise it to 2%, it would have to do so through the use of open market operations (in this case, because it wants to raise the rate, it would have to sell securities in order to reduce the money supply).
C) The Federal Reserve sets the target for the Federal funds rate, and then uses the reserve ratio to push banks toward that target.
Reserve requirements are perhaps the most powerful, and least often used, monetary policy tool that the Fed has at its disposal. It is very powerful because it directly increases or decreases the money supply.
For example, if the Fed wants to increase the fed funds rate, it can raise the reserve ratio so that banks keep more money in reserves, have less money to loan, and in consequence, create less money, causing the money supply to shrink and the fed funds rate to rise accordingly.
D) The Federal Reserve sets the Federal funds rate.
Correct. More specifically, the Federal Open Market Committee, which meets eight times a year to set the target for the fed funds rate.
The supply of loanable funds is $50 billion. Thus, option c is correct.
The supply of loanable funds considers only national savings( public savings + private savings), thus the supply of funds shall be only $50 billion. The national savings is the rate that measures the amount of income that households, business, and the government saves. It looks at the difference between a nation's income and consumption.
The national savings rate is the GDP that is saved rather than spent in the economy. It is an indicator of a nation's health as it shows the trends in savings.
Hence, option c is correct, that is $50 billion.

Answer:
True cost of the microwave is in 99% confidence interval: 
Explanation:
Relevant data:
As we want to know the 99% confidence interval, the significance level is:
We need to estimate a confidence interval by a two tailed normal bell. Then we have:
The z-value for a probability of 0.005 in a normal standard distribution is 2.576
Confidence interval is given by;:
True cost of the microwave is in 99% confidence interval:
