Answer:
Results are below.
Explanation:
Giving the following information:
The semiannual interest of 3.5%.
A) We need to calculate the nominal interest rate:
Nominal interest rate= 0.035/2= 0.0175
B) Real interest rate:
Real interest rate= (1.0175^2) - 1= 0.03531
It compounds interest twice a year. Therefore, is higher
C) Investment= $8,000
We will use the following formula:
FV= PV*(1+i)^n
n= 10
i= 0.175
PV= 8,000
FV= 8,000*(1.0175^10)
FV= $9,515.56
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,



Scarcity occurs when the demand for something exceeds the supply. Examples often occur with natural resources when they are over used. Think of over fishing, hunting or poor farming. The choice to over hunt in present may cost hunting opportunities in the future.
