Problem 1 (2 points). Every month a clothing store conducts an inventory and calculates the losses due to theft. The store would like to reduce these losses and is considering two methods to do so: the first is to hire a security guard and the second is to install cameras. The manager of the store has conducted the experiment: During the first 6 months he hired a security guard (method 1) and during the next 6 months he installed cameras (method 2). The monthly losses were reported as follows:

Security guard 350 289 407 398 470 259 Cameras 488 301 276 380 421 425

a/ Test with a=0.05 to determine whether there is enough evidence to conclude that expected monthly loss when installing cameras differs from 382. b/Since the cameras are cheaper than the guard, the manager would prefer to install the cameras unless there was enough evidence to infer that the guard was better. Conduct a hypothesis testing to advise what the manager should do? (Assuming equal variances and using a= 0.05)

Problem 2 (2 points). A supermarket chain performed a survey to help determine desirable locations for its new stores. The management of the chain wanted to know whether a linear relationship exists between weekly take home pay (s) and weekly food expenditures (y).

170 100 160 80 120 190 140 140 Y

a/ Find the least square regression line.

b/Perform the test Ho: Bi=0, H4: B10 (using a = 0.05) to determine whether there is enough evidence to infer that a linear relationship exists between weekly take home pay (s) and weekly food expenditures (y).

The migration pattern of Monarch butterflies are tracked by a catch-and-release method in which individual butterflies are tagged with a circular, lightweight sticker placed carefully on the wings so as not to impede their ability to fly. The sticker contains a unique ID number. Volunteers across the U.S. and South America capture the butterflies, record the IDs if they are tagged, and release them. This allows us to track the locations each unique ID is found, allowing us to estimate the migration pattern. On average, 1 out of 100 captured butterflies are already tagged. Suppose you are a volunteer and capture 50 butterflies; let $X$ denote the number of those that are already tagged. What is the distribution of $X ?$ What is the probability that you catch at least one tagged butterfly?

Plastic Co Pte Ltd (‘Plastico’) is a Fiji company. The company has issued and paid up capital of $250,000 held in equal parts by two brothers. The company’s business involves making plastic products for the local market.

The brothers are planning to emigrate to New Zealand and wish to sell the company. An agreement in principle is reached for X to buy the company for $1 million. This is a cash sale.

Presume that you are wealthy and a longtime friend of X.

X comes to see you. She explains that she has in hand $800,000 (from her own savings and bank financing) and is short $200,000 to close the deal. X wants you to loan her $200,000. X has two specific proposals as follows.

Proposal One

Plastico is an old company. When founded it established its factory on the outskirts of Suva. Since that time Suva has grown and spread with the consequence that the land on which the factory stands is today much more valuable than when the factory was built. X has had the land valued at $300,000.

X has found alternative factory premises on the outskirts of modern Suva that would be suitable for the company. These premises are for sale for $100,000.

X proposes that you lend her $200,000 for four months only. X will acquire Plastico. The company’s new directors, X and her husband, will have Plastico sell its current factory and relocate to the premises already identified. The relocation will provide net cash of $200,000. Plastico will then pay a dividend of $200,000. X will use the distribution to repay your loan.

Proposal Two

X proposes that you lend her $200,000. This will be a longer term loan of say 6 years to be paid down incrementally over the life of the loan. Plastico will retain its present factory premises. As security for the loan, Plastico’s new directors, X and her husband, will have Plastico grant you a first mortgage over the current factory premises. Given the valuation placed on the premises the loan will be almost risk free.

Further details of both proposals provide an attractive return for you on the financing.

Required:

Consider each proposal separately and in turn.

Does the proposal offend any of the capital maintenance rules?

[Note ‘agreement in principle’ refers to a situation where two parties have agreed on all the terms of a deal (i.e. contract) but have not yet formally committed to the deal. In this story the parties (X and the two brothers) will only sign the contact document detailing the agreement when X has lined up the required cash of $1 million.]
