The majority of this fraud is targeted the people who do not really pay attention to the specs of the product they use.
For example, many repairment targets older people by giving them advice to fix parts of their computer that's working fine.</span>
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,
<span>Implicit Cost Explicit Cost
The wholesale cost for the pianos that Darnell pays the manufacturer $452,000
The salary Darnell could earn if he worked as an accountant $48,000
The wages and utility bills that Darnell pays $301,000
The rental income Darnell could receive if he chose to rent out his showroom $38,000
B.
Profit ($)
Accounting Profit 842,000 - 452,000 - 301,000 = 89,000
Economic Profit 842,000 - 452,000 - 301,000 - 48,000 - 38,000 = 3,000
C. Economic Profit as an accountant = 48,000 + 38,000 - 89,000 = -$3,000. Thus, Darnell should stay in the Piano business to maximize the Economic Profit.</span>
