A project in South Korea requires an initial investment of 2 billion South Korean Won. The project is expected to generate net cash flows to the subsidiary of 3 billion and 4 billion won in the 2 years of operation, respectively. The project has no salvage value. The current value of the won is 1,100 won per U.S. dollar and the value of the won is expected to remain constant over the next 2 years. Calculate the net present value of this project if the required rate of return is 13 percent and the current exchange rate is 1,005 won per U.S. dollar.

1. Erving Goffman's concept of dramaturgy theorizes that when we interact with others we engage in a process of impression management wherein we actively work to present ourselves to others in particular ways. Which of the following are examples of this concept:

John puts on sweatpants to go out on a blind date

Tina rapidly runs a brush through her hair before running into work

James reads up on early Latin American art so as to appear knowledgeable in his class on the subject for the discussion

None of these are examples of impression management

All of these are examples of impression management

2. Andrew Ryan is looking at research on the level of conservatism of individuals (IV) and time spent on vacation (DV). He notices that there is a relationship between the two variables. Specifically, that the more conservative someone is the more time they will spend on vacations and that the less conservative someone is the less time they will spend on vacations. He therefore concludes that how politically conservative someone is causes them to spend more or less time on vacation. What concept is Andrew Ryan illustrating?

Quantitative Research

Research Bias

Inductive Research

Unethical Research

Correlation Does Not Equal Causation

3. W.E.B. Du Bois was famous for his blending of activism and academic research in order to create social justice for blacks in America. However, he recognized that in order to create a real change in social conditions for blacks, that:
Other minorities would need to band together to overthrow the racist government

Blacks would need to engage in a Civil Rights Movement

Other minorities would need to band together to overthrow the racist government

The Constitution would need to be amended Reparations would need to be made to every minority individual

Whites would need to create laws, economic and social conditions to change the situation of Blacks

Before each class, I either drink a cup of coffee, a cup of tea, or a cup of water. The probability of coffee is 0.7, the probability of tea is 0.2, and the probability of water is 0.1. If I drink coffee, the probability that the lecture ends early is 0.3. If I drink tea, the probability that the lecture ends early is 0.2. If I drink water, the lecture never ends early.
1) What’s the probability that I drink tea and finish the lecture early?
2) What’s the probability that I finish the lecture early?
3) Given the lecture finishes early, what’s the probability I drank coffee?

La Leche League International reports that the mean age of weaning a child from breastfeeding is age four to five worldwide. In America, most nursing mothers wean their children much earlier. Suppose a random survey is conducted of 21 U.S. mothers who recently weaned their children. The mean weaning age was 9 months (3/4 year) with a standard deviation of 3 months. Conduct a hypothesis test to determine if the mean weaning age in the U.S. is less than four years old. Conduct a hypothesis test at the 5% level.

Note: If you are using a Student's t-distribution for the problem, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.)

• Part (a)

  State the null hypothesis.

  H₀:

  μ ≤ 4

  H₀:

  μ = 4     

  H₀:

  μ ≠ 4

  H₀:

  μ > 4

• Part (b)

  State the alternative hypothesis.

  H_a:

  μ < 4

  H_a:

  μ ≠ 4     

  H_a:

  μ = 4

  H_a:

  μ > 4

• Part (c)

  In words, state what your random variable

  X

  represents.

  X represents the age at which American mothers wean their children.

  X represents the number of children weaned by age 4.

       

  X represents the average number of children weaned by age 4.

  X represents the average age at which American mothers wean their children.

• Part (d)

  State the distribution to use for the test. (Enter your answer in the form z or t_df where df is the degrees of freedom.)

• Part (e)

  What is the test statistic? (If using the z distribution round your answers to two decimal places, and if using the t distribution round your answers to three decimal places.)
  ---Select--- t z =

• Part (f)

  What is the p-value? (Round your answer to four decimal places.)
  
  
  Explain what the p-value means for this problem.

  If H₀ is false, then there is a chance equal to the p-value that the average age at which American mothers wean their children is equal to the sample mean or more.If H₀ is true, then there is a chance equal to the p-value that the average age at which American mothers wean their children is equal to the sample mean or less.     If H₀ is false, then there is a chance equal to the p-value that the average age at which American mothers wean their children is equal to the sample mean or less.If H₀ is true, then there is a chance equal to the p-value that the average age at which American mothers wean their children is equal to the sample mean or more.

• Part (g)

  Sketch a picture of this situation. Label and scale the horizontal axis and shade the region(s) corresponding to the p-value.

• Part (h)

  Indicate the correct decision ("reject" or "do not reject" the null hypothesis), the reason for it, and write an appropriate conclusion.(i) Alpha (Enter an exact number as an integer, fraction, or decimal.)
  α =  
  
  (ii) Decision:

  reject the null hypothesisdo not reject the null hypothesis     

  
  (iii) Reason for decision:

  Since α > p-value, we reject the null hypothesis.Since α < p-value, we do not reject the null hypothesis.     Since α > p-value, we do not reject the null hypothesis.Since α < p-value, we reject the null hypothesis.

  
  (iv) Conclusion:

  There is sufficient evidence to conclude that mean age at which American mothers wean their children is less than 4.There is not sufficient evidence to conclude that mean age at which American mothers wean their children is less than 4.     

• Part (i)

  Construct a 95% confidence interval for the true mean. Sketch the graph of the situation. Label the point estimate and the lower and upper bounds of the confidence interval. (Enter your answers in years. Round your answers to four decimal places.)

You work for a high-volume bakery and have been asked to develop a statistical model to predict and assess the quality of the bread product as it relates to the time and temperature of the manufacturing (baking) process. You have collected time temperature experimental data shown in the attached “BreadExp” data file. You have also noted the weather on the days the bread was baked with a 0-1 indicator variable. (0= Cool and dry, 1= Warm and wet). The response is a quality score metric called QScore.

1. [10 Points] Write the complete second order model with interaction that uses temperature and time as the explanatory variables.

2. [10 Points] Fit the regression equation for the model in Part 1 and submit the complete Minitab output. Include the sequential sums of squares in the output submitted.

I need to find the QS for time and temp to be able to fit the equation ?

Case 2: You have been hired as audit supervisor of KMR co. During the meeting you have been informed about the issues found in the organization after the process of audit risk assessment. You have been assigned for the audit of work in progress. You are also going to be a part of the team which will attend the year-end inventory count along with the final audit. The work in progress contains the cars which are partly assembled and the value of this is anticipated to be material. The company values work in progress in accordance with the percentage of completion. The standard costs are then considered and applied to the percentages calculated. The company hires an independent valuer for the valuation of work in progress. The partly assembled cars are then shipped to its subsidiary unit in America for completion and sales. The said inventory is in transit for 2 weeks. Required:

a. What factors the company should consider when placing reliance on the work of an independent valuer. (Marks 2)

b. What audit procedures should be adopted to ensure the correct record of WIP?

A temporary, six-month CSR position has just been filled at Dallas Distribution Center. The new hire is Abhey Patel, a very nice and bright person, who everyone agrees works extremely hard. Abhey has recently established citizenship in America from his homeland, India. Realizing the need to write to customers using proper English and grammar, the other CSRs have been covering for Abhey, proofreading his letters and e-mail messages for him. He is currently enrolled in an ESL (English as a Second Language) night class, but he hasn’t mastered all the fine points yet. Respond to these questions regarding Abhey’s situation:

1. What are some ways that Abhey can complete his duties on his own more easily?

2. Do you feel that the supervisor should be informed that Abhey has not yet developed his business writing skills and that others are helping him with his work? Is this practice of helping Abhey hurting his co-workers or the company?
