Newlands Brewery is evaluating a new product line for the production of two new cider brands for the young affluent target market. The brewery is currently operating at its optimal capacity and it will have to invest in an expansion for new machinery and production space. The expected cash flows for the two cider brands are:
Project Cider A, Cashflows are as follows , Year 0=(25 000), Year 1=12 900, Year 2=10 900, Year 3 =8 300 and year 4=7 240.

Project Cider B, Cashflows are as follows , Year 0=(13 500), Year 1=7 230, Year 2=8 200, Year 3 =8 600 and year 4=5 400

Also the expected net income figures for the new product line are as follows

Project Cider A net incomes Year 1=6 728, Year 2=4 800, Year 3 =2 009 and Year 4= 7 420

Project Cider B net incomes Year 1=3 855, Year 2=4 725, Year 3=5 255 and Year 4 =1 864

Consider the following information:
• The average book value for Cider A project is R12,500,000
• The average book value for Cider B project is R6,800,000
• Management requires 15 percent for the project to go ahead based on accounting rate of return perspective
• The discount rate for a project of similar risk level is 10 percent
• Management requires a minimum payback of 1.75 years for the type of risk associated with this project

Required:
Taking into consideration that the two projects are independent and no scaling issues, what should Newlands Brewery do? Your answer should be supported by the analysis of the following calculations:
• Payback method
• Discounted payback method
• Accounting rate of return (using averages)
• Net present value
• Internal rate of return
• Profitability index
Now consider the presence of scaling issue, which project should Newland Brewery consider?

Question
Dr. Gamble had been teaching PSYC 2021 for years, and always wore a suit to class. His average teaching evaluation across all courses and years was 4.2/5. As Dr. Gamble was preparing for an upcoming PSYC 2021 course (N = 132), he wondered whether his course evaluations would be lower than the average across all of his previous classes if he wore jeans and a t-shirt to every class in the upcoming term. Use null hypothesis testing (all steps) to determine if wearing jeans and a t-shirt will lower Dr. Gamble’s teaching evaluations, relative to the mean of all previous sections of the course. Note that only 59 of the 132 students completed a teaching evaluation. Be sure to appropriately interpret the confidence interval and effect size (even if it is subjective) and include a general summary of the results. Use α = .10. Show excel formula used.

Marge N. O’Hara, a senior analyst for a large stock brokerage has been tasked to forecast the weekly closing stock prices for this blue-chip stock for the first four weeks of next year. You are assigned to provide technical support to Ms. O’Hara. Weekly closing stock prices for all 52 weeks of this year for this blue-chip stock are reported in units of dollars ($). use mititab or excel 11. Prior to attempting ARIMA modeling, Ms. O’Hara wants to verify that differencing will make the weekly closing stock price data stationary. a. Present a time series plot of the first differences of the weekly closing prices. b. Does this plot appear to show horizontality? Explain why? c. Does this plot appear to show constant variance? (That is, overall, are the first differences of the weekly closing prices confined within a band?) Explain why? d. Can it be concluded that the first differences of the weekly closing prices stationary or nonstationary?

A manufacturer of raisin bran cereal claims that each box of cereal has more than 200 grams of

raisins. The firm selects a random sample of 64 boxes and records the amount of raisin (in grams) in

each box.

a. Identify the null and the alternate hypotheses for this study.

b. Is there statistical support for the manufacturer’s claim at a significance level of 5%? What

about at 1%? Test your hypothesis using both, the critical value approach and the p-value

approach. Clearly state your conclusions.

c. Under what situation would a Type-I error occur? What would be the consequences of a

Type-I error?

d. Under what situation would a Type-II error occur? What would be the consequences of a

Type-II error?

5.) Name all of the functions of inventory from your textbook. How are these functions affected by lead time, specifically whether lead times are very long, or relatively short? How does an increase, or decrease in lead time affect inventory carrying cost?

6.) Identify a project that you are interested in other than the fundraiser or job search we worked on in class. Identify the major steps of this project, and which of these are on the critical path. Then show the last step of the project and estimate the total time for the project. Use figure 17.3 from your textbook and Table 17.2 to help develop your answer. NOTE: Estimating the total project time will require developing a general understanding of what needs to be done between the first steps and the last step.

7.) If you were an operations manager for an organization (service or manufacturing) with at least 1,000 employees what three strategies would you use to make the operation as successful as possible? What is your rationale for each of the three strategies? What is one thing that might go wrong with each of these three strategies? Approach this question by first identifying a specific business, or type of business. (Note that if you are managing 1000 employees there will be a number of levels between you and the lower level employees. This is an operations question – so the response is related to operational challenges – not sales, marketing, finance, or accounting). Do not use Apple, Cargill, or Walmart.

8.) You are the owner of a small manufacturing company with 300 employees. What would be your top 5 operational strategies for making your company successful. (Do not use marketing, sales, accounting, or finance strategies). Give two specific reasons for choosing each of these five strategies (10 total reasons/justifications). Finally, give three reasons why you believe – not feel – these strategies would lead to success.

The Josephus problem is named after the historian Flavius Josephus, who lived between the years 37 and 100 CE. Josephus was a reluctant leader of the Jewish revolt against the Roman Empire. When it appeared that Josephus and his band were to be captured, they resolved to kill themselves. Josephus persuaded the group by saying, “Let us commit our mutual deaths to determination by lot. He to whom the first lot falls, let him be killed by him that hath the second lot, and thus fortune shall make its progress through us all; nor shall any of us erish by his own right hand, for it would be unfair if, when the rest are gone, somebody should repent and save himself” (Flavius Josephus, The Wars of the Jews, Book III, Chapter 8, Verse 7, tr. William Whiston, 1737). Yet that is exactly what happened; Josephus was left for last, and he and the person he was to kill surrendered to the Romans. Although Josephus does not describe how the lots were assigned, the following approach is generally believed to be the way it was done. People form a circle and count around the circle some predetermined number. When this number is reached, that person receives a lot and leaves the circle. The count starts over with the next person. Using the circular linked list developed in Exercise 6, simulate this problem.

Your program should take two parameters: n, the number of people that start, and

m, the number of counts. For example, try n = 20 and m = 12. Where does Josephus need to be in the original list so that he is the last one chosen?

Break-Even EBIT and Leverage Coldstream Corp. is comparing two different capital structures. Plan I would result in 3,700 shares of stock and $13,700 in debt. Plan II would result in 3,100 shares of stock and $30,140 in debt. The interest rate on the debt is 7 percent.

a. Ignoring taxes, compare both of these plans to an all-equity plan assuming that EBIT will be $7,600. The all-equity plan would result in 4,200 shares of stock outstanding. Which of the three plans hast the highest EPS? The lowest?

b. In part (a), what are the break-even levels of EBIT for each plan as compared to that for an all-equity plan? Is one higher than the other? Why?

c. Ignoring taxes, when will EPS be identical for Plans I and II?

d. Repeat parts (a), (b), and (c) assuming that the corporate tax rate is 40 percent. Are the break-even
levels of EBIT different from before? Why or why not?
