The complete question is as follows:
The admission directory of Big City University has a novel idea. He proposed using the IQ scores of current students as a marketing tool. The university agrees to provide him with enough money to administer IQ tests to 50 students. So the director gives the IQ test to an SRS of 50 of the university’s 5000 freshman. The mean IQ score for the sample is xbar=112. The IQ test he administered is known to have a σ of 15. What is the 95% Confidence Interval about the mean? What can the director say about the mean score of the population of all 5000 freshman?
Answer: The 95% confidence interval about the mean is 
.
The director can say that he is 95% confident that the mean IQ score of the 5000 freshmen lies between 107.84 and 116.16.
We follow these steps to arrive at the answer:
Since the population standard deviation of the IQ test is known, we can use the Z scores to find the confidence interval.
The formula for the confidence interval about the mean is:
In the equation above, X bar is known as the point estimate and the second term is known as Margin of Error.
The Critical Value of Z at the 95% confidence level is 1.96.
Substituting the values in the question in the equation above we have,
The lasting impact resulting from 20th-century banking reforms in the United States is "the reforms approved the Board to determine reserve requirements and interest rates for deposits at member bank."
The banking reforms made in the 20th century in the United States are many, and many of these reforms are still applicable today.
Some of the lasting effects of these reforms include the following:
The Board of Governors to determine the monetary policy.
The reforms established the Federal Deposit Insurance Corporation.
The reforms also separate commercial banks from investment banks.
Hence, in this case, it is concluded that the many banking reforms made in the 20th century still exist today.

Answer:
Predetermined manufacturing overhead rate= $9.8 per machine hour
Explanation:
Giving the following information:
Machine-hours= 50,000
Manufacturing overhead= $490,000
To calculate the predetermined manufacturing overhead rate we need to use the following formula:
Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base
Predetermined manufacturing overhead rate= 490,000/50,000= $9.8 per machine hour
Answer:
<em>a. True</em>
Explanation:
Yes! the given statement is <em>very true</em>, because as we know that all the level of a nation's rate of interest has an influence on the BOP ( generally known as Balance Of Payments ) financial account, and also relatively low real interest rates are generally encouraged.
An outflow of funds are been pursued at a higher interest rates in an another nation's currency as well.
