Assignment Code: 2012 GM03 B1                         Last Date of Submission: 15th October, 2012
                                            Maximum Marks: 100

Attempt all the questions. All questions are compulsory and carry equal marks

SECTION – A
1.    a) Distinguish between discrete and continuous probability distribution.
b) A dart player throws is given ten attempts to hit the bulls eye. He is had good practice and believes that he will be able to hit the bulls eye 90% of the time. What is the probability that he will have hit the bulls eye at least 6 times. State the assumptions you make while answering this question.  


2.    a) A batch of products is produced using two machines namely M1 and M2. It is believed that 30% of the products are produced using machine 1. Each machine is unable to produce all items which can be accepted. Hence Machine 1 produces only 94% of the products that can be accepted and machine 2 produces 98% of the products which can be accepted. One piece of the product is taken at random from the whole lot of production and is found to be defective. Find the probability that the defective piece found was produced by Machine 1.

b)It is found that a story book containing 200 pages contained on an average 2 spelling mistakes in every 10 pages. What is the probability that in the next 25 pages of the book that you read there will be more than 8 spelling mistakes. What is the expected number of spelling mistakes per 25pages and the variance in the spelling mistakes per 25 pages.    

3.    A company has given a contract to a bottling plant to fill its products with the product. The company has specified to the bottling plant that not more than 1% of the bottles should contain less than 980 ml of the product.
a.    Find the mean fill rate that the bottling plant must set so as to maintain the guideline stated by the company. The standard deviation is believed to be 40 ml per bottle.    
b.    The bottling plant has also found that it can install a machine which will reduce the standard deviation from 40ml to 10ml, but this needs to be replaced after filling 50000 bottles and it costs the company Rs. 30000. Each bottle of 1000 ml is sold to the company for Rs. 10. Should the bottling plant install this new machine ?



4.  The GMAT scores of students who are potential applicants to a university are normally distributed with a mean of 487 and a standard deviation of 98.
i.    What percentage of students will have scores exceeding 500?
ii.    What percentage of students will have scores between 600 and 700?
iii.    If the university wants only the top 75% of the students to be eligible to apply, what should be the minimum GMAT score specified for eligibility?
iv.    Find the narrowest interval that will contain 75% of the students’ scores.
Find x such that the interval [x,2x] will contain 75% of the students’ scores. (There are two answers. See if you can find them both.)   



SECTION- B 

A Company supplies pins in bulk to a customer. The company uses an automatic lathe to produce the pins. Factors such as vibration, temperature, and wear and tear affect the pins, so that the lengths of the pins made by the machine are normally distributed with a mean of 1.008 inches and a standard deviation of 0.045 inches. The company supplies the pins in large batches to a customer. The customer will take a random sample of 50 pins from the batch and compute the sample mean. If the sample mean is within the interval 1.000 ± 0.010 inch, then the customer will buy the whole batch.
1.    Find the probability that a batch will be acceptable to the consumer?
2.    If you were the manager of the company would be satisfied with the above level of probability and if not what would you think should be reasonable level of probability.
3.    If the lathe can be adjusted to have the mean length at any desired value, what should it be adjusted to achieve the probability you desire in part (2) above.

4. A manufacturer was making sport shirts for men. The manufacturer was mainly catering to the needs of Baseball, Basketball, and Football players. Their salesman had given a feedback to the company that the games for which the firm wanted to cater was equally applicable for both men and women and hence recommended that the firm should start making sport shirts for women as well. The firm collected data which are as follows:
      Gender    Baseball    Basketball    Football

Women    16    18    16
 Does the data suggest whether the requirement is  gender specific at 5% level of significance



SECTION-B

The debt-to-capital ratio of a company signifies the amount of financial risk a company is taking. If the ratio is high, the risk is high. This is because when the profit margin falls, debt will worsen the situation by making the return on capital fall even more adversely. The data on debt-to-capital ratio and return on capital for 12 different health care companies were collected and given in table below. Assume that this is a random sample of health care companies. Carry out a Regression analysis on the data for return on capital against debt-to-capital ratio and then answer the following questions.

1.  What is the regression equation.                             (3)

2.  Construct the ANOVA table and check the significance level of the regression model.    

3. Calculate the coefficient of correlation and test its significance at 5% level of significance.

Section B
Case Study: The Production Process in Vandana Enterprise

Vandana Enterprise Pvt. Ltd is owned by the Kumar family.  Mr Ramesh Kumar, the Managing Director and his daughter Vandana, jointly look after the company affairs.  Mr Gopal Kumar is the Chairman, but the day-to-day operations are handled by the father and daughter team.  There are about 300 employees and the sole aim of the company is to expand the market share in the textile market at home, as well as abroad.  Twenty-five years ago, when the company was started in a small town in Punjab, there were around 350 workers.  The company used indigenous and old technology to produce clothes.  Labour was mainly used while machines were used minimally.  The plants were modernized and mechanized over the years by acquiring the latest technology from  Japan and Europe, the result being that the number of machines were doubled and production quadrupled from 15,000 metres of cloth to about 62,000 metres of cloth everyday.  Vandana Enterprise had specialized till now only in the spinning and weaving of white linen and had no plans of changing the patterns of production.  However, after acquiring a modern machine from Japan, the company started planning the printing of bed sheets, pillow covers, etc., as a market for it existed all over India.  The company had, moreover, already established distribution channels and had significant presence.  Moreover, the South Asian, South-East Asian and Asia Pacific region proved to be a great export market.

Mr Kumar and Miss Kumar assumed that in order to increase their sales and make a bigger impact in the international market, the company had to improve on market information, regarding the specific needs and demands of customers in different markets.  The father and daughter team felt that the company had achieved maximum technical efficiency and the maximum production efficiency as the man-machine ratio was optimal.

Mr Gopal Kumar, Mr Ramesh Kumar’s older brother felt that mechanizing the plants further could increase the production capacity to a great extent (more than improving on market information).  Gopal Kumar didn’t mind retrenching some of the labour, but Ramesh Kumar and Vandana, thought the present man-machine ratio of 1;7:1 as maximum for the company, and the further import of the machine could not increase the production unless more people were hired – that too in exact accordance with the machines being bought/hired.  Hence, the best way to improve production and sales is by improving on market information, as there is unanimous decision of the management that at no cost will more workers will be hired.

Questions:

I    Can you comment on the returns to scale and factors (of production) of Vandana Enterprise, which the company experienced with mechanization of its plants?

II    When Mr. Gopal Kumar insists that production can be increased by further mechanization of the plants, what is the assumption regarding the production function that has to be valid?   (10+10=20)

Section B

Case Study: Cartel Formation by the Organization of
                         Petroleum Exporting Countries (OPEC)

OPEC is possibly the most renowned of all cartels.  It was established in 1960 by 5 major oil-exporting countries namely, Saudi Arabia, Iran, Iraq, Kuwait and Venezuela.  OPEC based itself on the principles of coordination and unification of the petroleum policies of member countries and the organization of means to ensure stabilization of prices, removing disadvantageous fluctuations.

Before 1960, countries producing oil had seen mounting/escalating clashes with international oil companies, which extracted oil under a concessionary agreement, whereby these companies could extract oil in return for royalties.  In effect, the oil producing countries had little say over the price, output and hence the revenue.  Till 1973, despite the existence of the cartel, OPEC member countries had virtually no control over oil production.

By 1973 with 13 members, i.e. Algeria, Gabon, Indonesia, Iran, Iraq, Kuwait, Libya, Nigeria, Qatar, Saudi Arabia, United Arab Emirates, Venezuela and Ecuador, the OPEC pricing policy through the 1970s comprised of setting a market price for Saudi Arabia (the market leader in terms of highest volume in production) and leaving other OPEC members to set their prices thereafter.

The cartel operated smoothly when demand conditions were buoyant.  The reasons for this being, that oil has an inelastic demand in the international market.  Consequently, the members earned huge revenues with a rise in price.  In 1973-74, after the Arab-Israeli War, OPEC increased the price from $ 3 per barrel to over $ 12 per barrel.  This was maintained till 1979-80.  Sales hardly showed a decline on account of the four-fold rise.  After the 1980 post - Iranian revolution, when the price was increased from $ 15 per barrel from $ 40 per barrel, the world demand dropped. This decline in demand was as a result to:

1.    Recession in the world economy (later, economists realized that recession was due to the soil shock itself).
2.    Steep rise in oil price resulting in conservation policies.  (For instance, lowering thermostats, switching to small fuel and efficient automobiles, etc).
3.    Expanded exploration and production by UK and Norway in the North Sea by USA in Alaska and by Mexico in newly discovered fields.  Switching to other sources of energy.

The result was a drastic fall in OPEC’s share of world oil production (from 55 to 60 percent in 1974 to less than 40 percent in 1994-95).

In order to restore its old glory, OPEC met frequently to settle aspects like oil prices and production quotas.  Hit by the harsh reality of declining demand, OPEC members settled down on a production ceiling of 16 million barrels per day to keep the price up.  This was the start of the break-up of the cartel.

Two trends were visible. On one hand, countries, which were densely populated and had low petroleum reserves like Nigeria, Indonesia and Iran wanted to charge high prices to maximize their short-run profit, while on the other hand, thinly populated and large reserve countries like Saudi Arabia and Kuwait preferred low prices to dissuade conservation and exploration of oil by bob-OPEC countries. They targeted long-term profits.  Prices declines in the world market and ranged between $ 15 and $ 20.  This prompted member countries like Venezuela and Nigeria to cheat by producing more than their quota.

With the glut in the oil market, OPEC could not regain its former glory, as it could not increase the price as desired.  There was a temporary surge in price after the Gulf War between Kuwait and Iraq, as the supply of oil was cut off from these two oil-rich countries.  No sooner had the war ended, the oil prices fell. Today the price of crude oil, in real terms stands at roughly $ 16 per barrel, while it was @ 2.50 per barrel in 1973.

OPEC clearly is trying to dominate the scene and new strategies are continuously devised to revive oil prices by strengthening oil quotas.  The reason for low oil prices have been already outlined.  On the demand side, the development of energy saving technology, plus a rise in fuel taxes have created a relatively slow growth in consumption.  On the supply side, there is a growing supply of crude oil by non OPEC countries and the adoption of a relatively high OPEC production ceiling of 24.5 million barrels per day from 1994-95.  All these factors have upset the demand-supply harmony.

The primary concern of OPEC members was how to make non-OPEC members control their production and how to stop some of them (OPEC members) from resorting to unethical production of more than the allotted quota.  A typical production by OPEC has been an over-production of 1 million barrels per day.

Questions:

I    What are the pre-requisites for cartel formation?  Is it possible to have cartels under all kinds of market structures?

II    Assuming that analysts predict a low future price of oil in the international market to continue for sometime, what should the likely impact on the OPEC be?                      (10+10=20)

Section B
Case Study

Case Study: XYZ Company

John Tan, the service manager, had Ram Lim as a supervisor in the equipment service section to oversee the work of the servicemen.  The supervisor was a nice person, but a bit soft in dealing with people.  After working for four years, Ram Lim left the company for a new job elsewhere.  A new supervisor was recruited from outside.

Roy Lee, a senior technician who had 10 years of service with the company, was disappointed because he was not considered for the supervisor’s post.  Robert had maintained a good record all along, and in fact, came up through the ranks from trainee to senior technician.

The new supervisor, Mehra, was generally a more aggressive person.  Shortly after taking over the job, he started asking his subordinates to record the actual hours spent on various activities and idle time, if any.  (Prior to this, the hours spent on each job were based on some kind of estimate.)  The technicians were not happy with this, but unwillingly complied with the demand.

The relationship between the supervisor and his workers deteriorated when Mehra started to change certain routine matters which were supposed to improve the flow of work and reduce overtime.

A few months later, two servicemen resigned.  Then the senior technician also tendered his resignation and complained to the service manager accusing Mehra of trying to create more work for them unnecessarily.  However, these complaints were found to be not fully justifiable, but to a great extent were the result of misunderstandings between Mehra and his men.

The service manager did not want to lose the senior technician, and managed to persuade him to stay on and reconcile with the supervisor.  Shortly after, the supervisor left the company.

Questions:

1.    Do you consider the actions taken by the new supervisor not tactful enough?  What would have been the tactful approach?

2.    There is a general tendency for employees to resist changes in routine, particularly when such changes may encounter initial teething problems and affect the morale of the employees.  In view of this, what should be the right approach in implementing changes?
                                                  (10+10=20)
