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:
$221,100
Explanation:
Given that,
Book value of equipment = $65,300
Sold at a loss = $14,000
Purchase of a new truck = $89,000
Sale of land = $198,000
Sale of Long term investment = $60,800
Cash flows from investing activities:
= Sale of Equipment - Purchase of a new truck + Sale of land + Sale of Long term investment
= ($65,300 - $14,000) - $89,000 + $198,000 + $60,800
= $51,300 - $89,000 + $198,000 + $60,800
= $221,100
Answer: Actual overhead costs always enter the Work-in-Process account.
Explanation:
The work-in-process account is an account where the value of goods yet to be completely produced are recorded while the overhead cost is simply a business running cost, that is cost on expenses the business makes to keep functioning.
Overhead cost is not recorded in work-in-process account, rather it is recorded as business expenses.
