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,
Because how do you know whether or not to accept the position. How do you know if it’s the right job for you? Or, what if you have to choose between two appealing offers? Will you feel comfortable with the people you work with?

In the command economic model, the government determines the level of economic productions in the country. It decides what will be produced, its quantity, and the cost price. A central authority or the government owns all the factors of production.

Answer:
b. $11250
Explanation:
Capitalized Cost of Equipment = $175,000
Life of Assets = 10 years
Residual value = $25,000
Depreciable value = Cost - Salvage value
Depreciable value = $175,000 - $25,000
Depreciable value = $150,000
Depreciation per year = Depreciable value / Life of assets
Depreciation per year = $150,000/10 years
Depreciation per year = $15,000
Depreciation from April to December 2021 = $15,000*9/12
Depreciation from April to December 2021 = $11,250
