In an environmental project, a ground source heat pump system will be installed, which will result in an annual fuel savings of 2000 HK$/year. The initial investment of the heat pump system is 14 000 HK$. The life-time of the heat pump system is 20 years. The annual maintenance cost is 300 HK$/year. At the end of the 20 years' life time, the salvage value is 1500 HK$. The interest rate is 10%.

(1) What is the net present value (NPV) of this investment?

(2) What is the benefit-cost ratio (BCR) of this investment?

(3) What is the internal rate of return (IRR) of this investment?

(4) Based on the above NPV, BCR and IRR values, please determine whether this investment is attractive or not?

Based on the above questions, please investigate and comment that how the "annual fuel saving" and its variation will affect the results of the above question. For example, the "annual fuel saving" varies +/- 0~300 HK$ based on the original 2000 HK$/year. (* two-page report is required)

Behavioural Aspects of Management Accounting   

Consider the following quotation from a factory worker:

“I’m on a piece rate. I get $4.20 on top of my hourly pay for every 100 mouldings I press. Normally I do about 1000 a day-it’s a good bonus. But the work is easy. I could do 2000. If I did, though, I know what would happen. Firstly, management would decide that the rate for the job was too generous, and would cut it. And secondly, if we all increased our production like that, half of us would soon be out of a job. So- take it easy, that’s my motto”.
from Elkin & Inkson (2000, p.109)

Required: (a) What is extrinsic and intrinsic motivation?   

(b) What are the intrinsic and extrinsic motivating factors that are involved in the situation above?  

(c) What is goal congruence and is it being achieved in the above situation?

(d) Suggest two ways in which the factory worker could be encouraged to increase production?

The average monthly rent for a 1-bedroom apartment in San Francisco ranges from approximately $2500 to $3700, depending on the neighborhood. A rent control policy setting $2000 per month rent on apartments is being considered in San Francisco, where the demand for apartments is given by P = 5000 − Q and the supply of apartments is P = 1000 + Q. Here, P = dollars of monthly rent, and Q = number of apartments available for rent. For purposes of this analysis, apartments are treated as identical. (a) (4 points) What is the current market equilibrium price and quantity before the rent control is imposed? (b) (10 points) Now impose the rent control of P = $2000. Draw a market demand and supply graph and label the equilibrium price and quantity from part (a), the rent control price, and the number of apartments actually rented under the rent control policy. What is the change in consumer surplus, comparing the market equilibrium to the market with rent control? Label consumer surplus before and after rent control is imposed and show your work

In a large midwestern university (the class of entering freshmen is 6000 or more students), an SRS of 100 entering freshmen in 1999 found that 20 finished in the bottom third of their high school class.  Admission standards at the university were tightened in 2000.  In 2001, an SRS of 100 entering freshmen found that 10 finished in the bottom third of their high school class.  Let p1 and p2 be the proportion of all entering freshmen in 1999 and 2001, respectively, who graduated in the bottom third of their high school class.

Is there evidence that the proportion of freshmen who graduated in the bottom third of their high school class in 2001 has been reduced, as a result of the tougher admission standards adopted in 2000, compared to the proportion in 1999?  To determine this, you test the hypotheses

H0: p1 = p2, Ha: p1 > p2.

The z-test statistic is approximately 1.98, find the P-value, using a Standard Normal Table or your calculator.

Here, you will state whether you agree or disagree with fiscal and monetary policy actions taken in the 2000’s (2000-2010).

Fiscal Policy actions:

The Economic Stimulus Act of 2008

American Recovery and Reinvestment Act of 2009

Monetary Policy actions:

The Federal Open Market Committee

• It is possible that some actions you agree with and other you disagree with - that is fine. You can discuss your reasons for disagreement or agreement on a case-by-case basis.
• In your argument, be sure you are using our economic models and concepts to support you and not just your own opinion or feeling about what is best. For instance, saying that we should not have spent money on government programs because it's not fair to give out money to people would not be an macroeconomics-based reason. You could say that increased government spending through expansionary fiscal policy created too much inflation later on and so you disagree with that action.

The previous question was:

Annual salaries for a large company are approximately normally distributed with a mean of 49000 dollars and a standard deviation of 2000 dollars. One manager claims that all of his direct reports are paid "above the 75th percentile" for the company. What is the minimum dollar figure of employees working under this manager?

I used qnorm(o.75, 49000, 2000) to get an answer of $50,348.98 for the minimum dollar figure for employes under that manager.  

The current question:

Part 1: Create a neat, annotated, complete normal density plot representing the second part of the above question with the primary x-axis set to X.

I am struggling with the code for this question.  

Part 2: add a secondary x-axis to the plot from above, showing the Z values that correspond to the x-values of the first axis.  

Please show all code to obtain results.  

Fill in all the underlined spots on the spreadsheet with the data about Absorbance of Light for different Nitrate Levels. The goals are: 1) to compute the correlation and slope of the regression line by using the "SS formulas" and 2) to compute SSE, the sum of the squared "errors" (residuals).

Power Scru, LLC produce three different Models of power washer. A Limitation of 2000 machine hours associated with equipment necessary for making a key component of all three models of the power washers prevents Power Scrub from meeting the sales demand for all of its power washers.
