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: 10% or $2,000,000
Explanation:
Seeing as no figures were produced, we will have to do this ourselves.
We will make assumptions which include the following,
Life of the equipment = 10 Years
Salvage value = 0
Those are our 2 assumptions.
In that case then,
The Annual Depreciation will be,
Depreciation = (Cost of equipment - Estimated salvage value) / Estimated useful life
= (20 - 0) / 10
= $2 million
Seeing as 2 million is,
= 2/20 * 100
= 10%
That would mean that annual depreciation costs at that facility will rise by $2 million or 10%.

Answer:
71.57 days
Explanation:
For computing the average collection period first we have to determine the account receivable turnover ratio which is shown below:
Account receivable turnover ratio = Credit sales ÷ average accounts receivable
where,
Average accounts receivable = (Opening balance of Accounts receivable + ending balance of Accounts receivable) ÷ 2
= ($75,000 + $83,000) ÷ 2
= $79,000
And, the net credit sale is $403,000
Now put these values to the above formula
So, the answer would be equal to
= $403,000 ÷ $79,000
= 5.10 times
Now
Average collection period in days = Total number of days in a year ÷ accounts receivable turnover ratio
= 365 days ÷ 5.10 times
= 71.57 days
