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:
the budgeted selling and administrative expenses for July is $64,100
Explanation:
The computation of the budgeted selling and administrative expenses for July is shown below:
= Budgeted selling & admin cost + (per unit sold × July units)
= $20,000 + ($9 × 4,900 units)
= $20,000 + $44,100
= $64,100
hence, the budgeted selling and administrative expenses for July is $64,100
We simply applied the above formula
Answer:
The equipment's net book value on 12/31/2015 is $ 135000.
Explanation:
Net book value of the equipment on 12/31/2015 is given by:
Net book value = cost of the equipment - depreciation expense recognized until 12/31/2015
= $ 350000 - $ 215000
= $ 135000
Therefore, the equipment's net book value on 12/31/2015 is $ 135000.

Answer:
2) assumption not made
Explanation:
The original statement does not include any assumption about what the companies are doing about this issue, it just proposes an idea of fair compensation.
maybe whoever wrote this statement believes that very few companies or none at all actually compensate homeowners for a reduction in the market value of their properties, but it doesn't state it. It is also possible that the statement assumes that companies are paying some compensations or were paying some compensations but are not willing to continue to do it since no legislation forces them to do so. The author's position is vague and not clear with respect to what the companies are currently doing.
