Suppose the test scores of 75 students in a class follows normal distribution with a standard deviation of 3. The sample mean is 68. What distribution is used in constructing confidence intervals in this problem?
Answers
The Correct answer is that the normal distribution is used in constructing confidence intervals in this problem.
Confidence intervals are calculated based on the sample mean and standard deviation. In this case, since the sample size is large enough (n>30), the central limit theorem applies and the distribution of the sample mean is approximately normal
When dealing with a normally distributed population where the standard deviation is known, we would typically use the Z-distribution to construct confidence intervals. However, in this case, we have a sample of 75 students and are given the sample mean (68) and sample standard deviation (3).
Since the population standard deviation is not provided, we must use the t-distribution for constructing confidence intervals. The t-distribution is appropriate when dealing with smaller sample sizes and unknown population standard deviations.

67) If you receive $1,000 payment at the end of five years, what
type of cash flow do you have?
- perpetuity
- annuity due
- single cash flow
Answers
If you receive a $1,000 payment at the end of five years, then it is a single cash flow.
A single cash flow refers to a one-time payment received or made at a specific point in time. Receiving a $1,000 payment at the end of five years represents a single cash flow. It does not involve a series of regular payments or a continuous stream of cash flows.
Perpetuity refers to a never-ending series of equal cash flows, while annuity due involves a series of regular payments received or made at the beginning of each period. However, in this case, there is only a single payment at the end of the specified period, making it a single cash flow.
The $1,000 payment received after five years is a one-time occurrence, indicating a single cash flow rather than perpetuity or annuity due.

Show graphically the abnormal profit (economic profit) area of the pure competition firm in the short run.
Answers
The graph showing economic profits is in the image.
Perfect or pure competition is explained as "a condition in an industry where that industry is composed of many tiny firms providing homogenous products, when there is no barrier to the entry or leave of firms, and when full data is available."
In the short-run, the pure or perfect competition profit of a firm go up to the maximum position in situations where marginal revenues (MR) equals to the marginal cost (MC).
When the price (P) is higher than average cost (AC) for a given period of time, the firm can generate abnormal or economic profits in the Short run.
The difference between abnormal and normal profit is related to the link between average total cost and average market price, and abnormal profit can only be produced when average revenue is higher than average total cost. It's crucial to keep in mind, though, that not every business has the ability to make earnings that are above average
The characters in the graph stands for:
D = Demand in the market
MR = Marginal Revenue
MC = Marginal Cost
ATC = Average Total Cost

For $100, the amount of video games delivered and the quantity of video games sought are equal to 200 = 200.

The producer or seller can sell as many units as they want, and the buyer can buy as many as they want. In economics, the equilibrium price is found by squaring the supply and demand functions and solving for the price. The point at where the supply and demand curves cross is known as the equilibrium point. The point indicates the best price and quantity.

B. Conscientiousness at work
C. Extraversion
D. Emotional stability and openness at work
Answers
Rose believes that happiness at life leads to happiness at work, according to her belief, she is characterized by a high extraversion. The correct option is c) Extraversion.
As a successful PR, her ability to befriend clients and encourage them to invest in the business demonstrates her outgoing and sociable nature, which are key traits of extraversion. She excels at building relationships and persuading people, making her an ideal candidate to handle tough clients.
Extraverts tend to be confident, assertive, and energetic, which allows them to navigate social situations with ease. In the context of Rose's job, these qualities help her secure deals and achieve success at work. Moreover, her belief that happiness in life leads to happiness at work further reflects her optimistic and positive outlook, another characteristic of extraversion.
While conscientiousness and openness at work (A) are important traits for success in various fields, these are not the primary characteristics that set Rose apart as a PR professional. Similarly, conscientiousness at work (B) alone does not capture her unique ability to build relationships and persuade clients.
Lastly, emotional stability and openness at work (D) may contribute to her overall well-being, but they do not directly relate to her success in connecting with clients and securing deals. Therefore, the most appropriate answer is Extraversion (C), which highlights her exceptional social skills and optimistic nature that ultimately drive her success in the PR industry. The correct option is c) Extraversion.

You are asked to evaluate the following two projects for the Norton corporation. Use a discount rate of 10 percent. Use Appendix B for an approximate answer but calculate your final answer using the f
Answers
Since PV(B) > PV(A), Project B seems to have a higher value and appears more favorable for Norton Corporation's investment decision.
To evaluate the two projects for Norton Corporation, we will use a discount rate of 10 percent. Let's examine the projects:
Project A:
Initial Investment: $50,000
Annual Cash Inflows: $10,000 for five years
Project B:
Initial Investment: $80,000
Annual Cash Inflows: $20,000 for four years
To determine the present value (PV) of each project, we need to discount the cash inflows at a rate of 10 percent. Using Appendix B, we find that the discount factor for five years at 10 percent is approximately 0.621, and for four years, it is 0.683.
Project A's PV is calculated as follows:
PV(A) = $10,000 × 0.621 + $10,000 × 0.621^2 + $10,000 × 0.621^3 + $10,000 × 0.621^4 + $10,000 × 0.621^5 ≈ $27,868
Project B's PV is calculated as follows:
PV(B) = $20,000 × 0.683 + $20,000 × 0.683^2 + $20,000 × 0.683^3 + $20,000 × 0.683^4 ≈ $52,522
Finally, we compare the present values to evaluate the projects. Since PV(B) > PV(A), Project B seems to have a higher value and appears more favorable for Norton Corporation's investment decision.
