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,
Answer:D

Answer:
Option (A) is correct.
Explanation:
Cash flow from Operating Activities:
= Net income + (Beginning Accounts receivable - Ending Accounts receivable) + (Ending Accounts payable - Beginning Accounts payable)
= $45,000 + ($23,000 - $22,000) + ($28,000 - $26,000)
= $45,000 + $1,000 + $2,000
= $48,000
Therefore, Bird Brain's cash flows from operating activities would be $48,000.
The answer that best fits the blank space in the question is (A) city.
Infrastructure generally refers to <em>the essential facilities and systems that serve an area, which can apply to a city, country, or even smaller regions such as a village</em>.

Explanation:
Customer access strategy is a framework or a set of standards, guidelines and processes, which defines the means by which a customer and the organization can interact, and means by which the customer has access to:
- the relevant information needed to make purchases
- the right logistics for the execution of a purchase
The arear of access are mainly information (value of the product, price of products, how products work) and logistics (means of getting the products, customer service on the after-purchase needs etc).
It has been studied extensively that companies are spending 3 to 4 times as much money on creating customer access than they do on advertising, this is because even if advertising is successful, the results will not be seen if customer access is not successful, and having an efficient customer access strategy can provide a competitive advantage to the producers.
