Assignment 1 (12 questions)

1. Suppose you discover a treasure chest of RM10 billion in cash

a. Is this a real or financial asset?

Answer:

Yes. 10 billion cash is the financial asset. This is because financial assets only obtain its monetary value from a contractual agreement of what it represents. In contrast, real asset itself has the physical value.

b. Is society any richer for the discovery?

Answer:

No. This is because the cash does not contribute to the productive capacity of the economy.

c. Are you wealthier?

Answer:

Yes. You would become wealthier with RM10 billion cash.

d. Is anyone worst off as a result of the discovery?

Answer:

Yes. The society as a whole is worse off. This is because cash is the financial asset and it becomes is a liability of the government upon the time you found the cash. So, the taxpayers will have to make up for the government liability.

2. The average rate of return on investment in large stocks has outpaced that on investments in T-Bills by about 8% since 1926 in US. Why, then, does anyone invest in T-Bills?

Answer:

This is because T-bill is regarded as an almost risk free asset as it is backed by the government. Therefore, it has lowest volatility as compared to stocks. This is also a reason that people tend to invest in T-bills instead of stocks.

3. You see an advertisement for a book that claims to show how you can make RM1 million with no risk and with no money down. Will you buy the book? Why?

Answer:

No. It is impossible to make RM1million with no risk and with no money down. This is because only a person who takes risk would be compensated…...

...Problems and Exercise Questions for Week 4 1. Chapter 7, Problems/Exercises, Questions 5, 16, and 17 (post in the “Week4: Problems and Exercise” DropBox). 5. Study the E-R diagram of Figure 7–20. Based on this E-R diagram, answer the following questions: (5 points) a. How many PROJECTs can an employee work on? As we see the sign for mandatory many there are 2 entity with 2 entity type b. What is the degree of the includes relationship? Between Tool and Task we got Binary Relationship Many to many if say” tools”, otherwise it will be one to many. c. Are there any associative entities on this diagram? If so, name them. No. between tools and city we do not need to have any associative entities. An associative entity is a relationship that the data modeler chooses to model as an entity type d. How else could the attribute Skill be modeled? We can use a multivalued attribute may take on more than one value for each entity Project _ID-Employee_ID Task_ID all in one box e. Is it possible to attach any attributes to the Includes relationship? Tasks require Time and Skill, and have to be done in the city by an employee who has an ID and carries tools. f. Could TASK be modeled as an associative entity? Yes it can as our book explain: An entity type that associates the instances of one or more entity types and contains attributes that are peculiar to the relationship between those entity instances. 16.

...EXERCISE 36 Questions to be graded 1. The researchers found a significant difference between the two groups (control and treatment) for change in mobility of the women with osteoarthritis (OA) over 12 weeks with the results of F(1, 22) = 9.619, p = 0.005. Discuss each aspect of these results. * The F-value suggests that there is a significant difference between the results of the control and treatment groups. The P-value of 0.005 is < the alpha of 0.05. This suggest that the groups are significantly different and the null hypothesis should be rejected. 2. State the null hypothesis for the Baird and Sands (2004) study that focuses on the effect of the GI with PMR treatment on patients’ mobility level. Should the null hypothesis be rejected for the difference between the two groups in change in mobility scores over 12 weeks? Provide a rationale for your answer. * Treatment group mean = control group mean * With the p-value being < the alpha, the null hypothesis would be rejected indicating the difference in the mean mobility scores. 3. The researchers stated that the participants in the intervention group reported a reduction in mobility difficulty at week 12. Was this result statistically significant, and if so at what probability? * The p-value of 0.005 suggests that the results are statistically significant. 4. If the researchers had set the level of significance or α = 0.01, would the results of p = 0.001 still be statistically significant?......

...ANSWERS TO End-of chapter QUESTIONS AND exercises Answers to Questions for Review 1. (Explicit and Implicit Costs) Amos McCoy is currently raising corn on his 100-acre farm and earning an accounting profit of $100 per acre. However, if he raised soybeans, he could earn $200 per acre. Is he currently earning an economic profit? Why or why not? Amos McCoy is not currently making an economic profit, despite the fact that he is making an accounting profit. This is so, because the accounting profit calculation does not take into account an important implicit cost—the opportunity cost of not raising soybeans. Actually, McCoy is experiencing an economic loss. According to our theory, he should get out of the corn business and begin growing soybeans. This question highlights the important distinction between accounting profit and economic profit. 2. (Explicit and Implicit Costs) Determine whether each of the following is an explicit cost or an implicit cost: a) Payments for labor purchased in the labor market b) A firm’s use of a warehouse that it owns and could rent to another firm c) Rent paid for the use of a warehouse not owned by the firm d) The wages that owners could earn if they did not work for themselves a) explicit; b) implicit; c) explicit; d) implicit 3. (Alternative Measures of Profit) Calculate the accounting profit or loss as well as the economic profit or loss in each of the following situations: ...

...Chapter 1 Problems and Exercises 1. By following the system analysis and design methodologies you will be able to answer questions for the end user because you are going to build the system and design it to the end user. For example you build a system for tracking inventory and train the managers how to use it so they know what inventory is available. You don’t want to build the system in a quick and easy format because then it might not perform up the tasks that are required of it. By using the engineering approach I will be using the input from the users of the system to build a proper system that will benefit the current and future users. Also it will allow me to use current tools available to make sure the programs are functioning as required. 8. Prototyping during the SDLC life cycle may be incorporated in any of the 2nd and 3rd phases. You would create the prototype during the 2nd phase and then revamp it during the 3rd phase, and in the final phase it would be implemented. I feel that these two styles do not really mix that well but if necessary you could use prototyping during the SDLC process. Chapter 2 Problems and Exercises Q3. I would say all 8 are still important but the top 2 that I would use to make the final decision is Vendor support and Viability of Vendor Vendor support is just what it says, the support that the vendor will supply with the building and implementing of the software. And Viability of Vendor is how long the......

...EXERCISE 11 Questions to be Graded 1. What demographic variables were measured at least at the interval level of measurement? Age (yrs), Income (annual)($), Length of labor (hrs), Return to work (wks), and Number of hours working per week were measured at least at the interval level of measurement 2. What statistics were used to describe the length of labor in this study? Were these appropriate? The variable length of labor were used to describe by ratio data that can be described by using mean, range, and standard deviation. it is also called as interval/ratio level data 3. What other statistic could have been used to describe the length of labor? Provide a rationale for your Answer. Nominal level data could be used to describe the length of labor. This would have done by using frequencies, percentages, and mode instead of using mean, range, and standard deviation 4. Were the distributions of scores similar for the experimental and control groups for the length of labor? Provide a rationale for your answer. It is different, because the mean of the experimental group is 14.63 while the mean of the control group is 12.79standard deviation of the experimental group is 7.78 and control group is 7.2 5. Were the experimental and control groups similar in their type of feeding?

...EXERCISE 24 Questions to be Graded 1. What is the r value listed for the relationship between variables 4 and 9? r = -0.32 2. Describe the correlation r = −0.32** using words. Is this a statistically significant correlation? Provide a rationale for your answer. This represents a moderate negative relationship. It is statistically significant at the 1% level of significance as indicated in the table. (** p < 0.01) 3. Calculate the percentage of variance explained for r = 0.53. Is this correlation clinically important? Provide a rationale for your answer. variance = r^2 = (0.53)^2 = 0.2809 = 28.1% This is clinically important since any variance over 9% is considered clinically important. 4. According to Table 2, r = 0.15 is listed as the correlation between which two items? Describe this relationship. What is the effect size for this relationship, and what size sample would be needed to detect this relationship in future studies? This is between variables 3 and 7. It represents correlation between Positive Items and Avoidance. There is a weak correlation here because r < 0.3. The effect size is 0.15. The sample size required in this case would be 273 (given a power of 0.8). 5. Calculate the percentage of variance explained for r = 0.15. Describe the clinical importance of this relationship. variance = r^2 = (0.15)^2 = 0.0225 = 2.25% This is not considered clinically important since the variance is less than 9%. 6.
