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 contribution margin approach helps managers in short-tern decision making because it reports costs and revenues at their current value.
The contribution margin ratio/approach allows companies to determine their profits they can make from a product minus variable costs.
<span>Process costs are costs that limit the occurrence of defects and imperfections. Process costing is an accounting methodology that traces and accumulates direct costs, and allocates indirect costs of a manufacturing process. ... It is a method of assigning costs to units of production in companies producing large quantities of homogeneous products.</span>
Answer:
Your project is split into two teams across two different continents. They understand the work to be completed, as well as communication processes. But they still often argue about how the work should be accomplished and who should make decisions. Given what you know, what is the most likely cause for these issues?
cultural differences

Answer:
The correct answer is (B)
Explanation:
Economists are helpful to predict future economic and financial phenomenon’s. In that regard, statistical or mathematical models are considered more appropriate and it is said that they provide better results. In the above scenario, Syd is attempting to construct an economic model for that, the suitable technique to examine the cause and effect to predict the outcomes are mathematical functions. The reason is that mathematical models are more appropriate to predicts cause and effect.
