How do you know if you use z-test or t-test?
Answers
The decision to use a z-test or t-test depends on several factors, such as the sample size, the population standard deviation, and the level of significance.
If the sample size is large (typically above 30), and the population standard deviation is known, then a z-test can be used. On the other hand, if the sample size is small (typically less than 30), and the population standard deviation is unknown, then a t-test is appropriate.
Additionally, if the level of significance is very high or very low, a z-test may be more appropriate since it assumes a normal distribution. However, if the sample size is small and the population distribution is unknown or non-normal, a t-test may be more appropriate.
Ultimately, the choice of which test to use should be based on the specific circumstances of the study and the assumptions of each test.

What can be a benefit of using interviews to select employees to hire?
A. Insights from employees' examples
B. Accurate prediction of honesty
C. Good measurement of intelligence
D. Errors from employee bias
Answers
Answer:
B. Accurate prediction of honesty
Explanation:
Interviews are one of the most effective tools that human resource managers use to determine if a candidate is a match or not for a specific job. Flexibility is the key word here. That allows both the candidate and the interviewer, the possibility of understanding what are the skills needed for a certain job and if the candidate possesses them. When someone answers a test, you can tell if the candidate knows about the subject or not, but when he/she is interviewed, you can ask for more detail and examples that help clarify the candidate's ideas, expectations and capabilities. E.g. a candidate states that he/she knows how to use WordPress very well, and the interviewer can ask him/her about specific tasks to verify if that is true.

A. Insights from employees’ examples

B.the liabilities of the First National Bank decrease by$10.
C.the liabilities of Citibank decrease by $10.
D.the reserves of the First National Bank increase by $10.
Answers
The appropriate response is: When a $10 check made out to First National Bank of Chicago is placed in an account at Citibank:
B. The First National Bank's liabilities are $10 lessened.
Due to the fact that the First National Bank will get the cheque for payment when it is deposited at Citibank, this is true. The check will be paid, which will result in a $10 reduction to the First National Bank account from which it was taken, lowering First National Bank's obligations. Then, a $10 increase in the deposit at Citibank will take place; however, Citibank's liabilities are unaffected.

Assume that banks hold no excess reserves and that all currency is deposited into the banking system. if the required reserve ratio is 25.00%, and the Federal Reserve wants to increase the money supply by $60.00 million, the Fed would need to make an open market purchase of $ _______ million. (insert your answer in millions, and round to two decimal places.)
Answers
The Fed would need to make an open market purchase of $15.00 million to increase the money supply by $60.00 million, assuming banks hold no excess reserves and all currency is deposited into the banking system.
If the required reserve ratio is 25%, then banks must hold 25% of deposits as reserves and can loan out the remaining 75%. Therefore, if the Federal Reserve wants to increase the money supply by $60 million, banks would be able to lend out $60 million / 0.75 = $80 million in total.
To calculate the required open market purchase by the Fed, we need to use the money multiplier formula:
Money Multiplier = 1 / Reserve Ratio
So, in this case, the money multiplier would be 1 / 0.25 = 4.
To increase the money supply by $60 million, the Fed would need to purchase $60 million / 4 = $15 million worth of securities in the open market.
Therefore, the Fed would need to make an open market purchase of $15.00 million (rounded to two decimal places) to increase the money supply by $60.00 million, assuming banks hold no excess reserves and all currency is deposited into the banking system.

In what way is Paul Krugman’s perspiration theory related to Al Young and Larry Lau’s research on Asian economic growth?
Answers
Paul Krugman's "perspiration theory" and Al Young and Larry Lau's research on Asian economic growth are related in the sense that they both emphasize the importance of hard work, effort, and investment in driving economic development.
Paul Krugman's perspiration theory, also known as the "new trade theory," suggests that sustained economic growth and competitiveness are achieved through persistent efforts, investments in research and development, and continuous innovation. According to Krugman, countries need to actively pursue strategies to enhance their productivity, develop comparative advantages, and promote industries that can compete globally.
Al Young and Larry Lau's research on Asian economic growth, on the other hand, focuses specifically on the experiences of Asian countries, particularly the "Asian Tigers" such as South Korea, Singapore, Taiwan, and Hong Kong. Their research highlights the role of factors such as education, human capital development, investment in infrastructure, technology adoption, and institutional support in driving rapid economic growth in these Asian economies. They emphasize the importance of long-term planning, strategic investments, and the dedication of resources towards enhancing productivity and technological advancement.
Both perspectives converge on the idea that economic growth requires deliberate efforts, investments, and a focus on productivity enhancement. They emphasize the significance of factors such as human capital development, technological progress, and targeted policies to foster economic competitiveness.
Thus, Krugman's perspiration theory and Young and Lau's research share a common emphasis on the role of hard work, investment, and productivity improvement in driving Asian economic growth.
