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:
Explanation:
Selling price per unit (next year) = 30 + 10 % of 30 = $33
Variable cost per unit (next year) = 30 * 40 % = $12
Contribution per unit (next year) = Selling price per unit (next year) - Variable cost per unit (next year) = 33 - 12 = $21
Fixed expenses = $68,250
Break even point (in units) = Fixed expenses / Contribution per unit.
Break even point (in units) = 68,250 / 21
= $3,250
Answer:
$6,750,000
Explanation:
Since it is stated in the question that the 3mn shares will be paid the principal and interest at maturity, and it is not stated the note is compounded, we apply the following simple calculation:
Amount to pay = $4,500,000 + [($4,500,000 × 10%) × 5 years]
= $4,500,000 + [$450,000 × 5 years]
= $4,500,000 + 2,250,000
Amount to pay = $6,750,000
Therefore, the amount should be paid to the stockholders at the end of the fifth year is $6,750,000.
Answer:
The rewards and punishment serve the purpose of motivating the employees.
Explanation: First of all, we must establish that companies should have set guidelines or principles on which they operate, especially when it comes to ethics and acceptable workplace behavior.
Secondly, we must acknowledge the fact that there is always a reward or consequence for our actions. Especially in the workplace where employees are constantly monitored.
Now, based on the Theory X of management that was developed by Douglas McGregor, which basically states that employees are unmotivated and unwilling to work, and as a result of this, they need to be constantly prompted, rewarded or punished to make sure that they complete their tasks.
So to answer the question, the rewards and punishments serve the purpose of motivating the employees to be of good conduct in the workplace, because if this is not done, bad behavior might spread throughout the company and this will cause further problems.
