1. Find the appropriate values of n1 and n2 (assume that n1 = n2) needed to estimate (?1 ? ?2)
with following:
(a) A sampling error equal to 3.2 with 95% confidence. From prior experience, it is known that
?1 =15and ?2 =17. 1 ?
(b) A sampling error equal to 8 with 99% confidence. The range of each population is 60.
(c) A 90% confidence interval of width 1.0. Assume that ?12 = 5.8 and ?2 = 7.5. 7.
2.Two surgical procedures are widely used to treat a certain type of cancer. To compare the
success rates of the two procedures, random samples of the two types of surgical patients were
obtained and the numbers of patients who showed no recurrence of the disease after a 1-year
period were recorded. The data are shown
n >number of successes
procedure A >100 81
procedure B >100 79
How large a sample would be necessary in order to estimate the difference in the true success
rates to within .10 with 95% reliability?

1. LaTasha has started her own custom T-Shirt company, T\'s T\'s, which produces silk screened T-shirts for various occasions and organizations; as well as a brisk walk-in trade. Her shop is located in a small beach community in Florida. Since she has just started she is renting the equipment from a large firm in Jacksonville. The cost of renting the equipment is $500. The material used in one custom T-shirt costs $4.50, and LaTasha is selling the T-shirts for $12 each. a. If LaTasha sells 50 shirts, 1. What will her total revenue be? 2. What will her total cost be? b. How many shirts must LaTasha sell to break even? c. What is the total revenue at the break-even point? Solution 1. The total revenue is equal to the amount of income gained by selling the 50 shirts, not accounting for any expenses (which net profit or net income values take into account). The T- shirts are sold for $12 each, so one T-shirt costs $12, two T-shirts cost 2 times $12 = $24, and so on. If 50 T-shirts are sold: Total Revenue = (50 T-shirts) ($12 per T-shirt) = $600 2. Her total cost is equal to the amount she has to pay. First, she must rent equipment for $500, which she pays, and she must also pay $4.50 for each T-shirt that she buys (and may or may not sell). Her total cost is the sum of the costs of the equipment and the T-shirts: Total Cost = $500 + (50 T-shirts) ($4.50 per T-shirt) = $500 + $225 = $725 b) In order to break even, the total revenue must equal the total cost. If x is the number of T- shirts needed for LaTasha to break even, her total revenue must equal her total cost. Her total revenue is given by 12x ($12 per each T-shirt), and her total cost is given by 500 + 4.50x ($500 rent plus $4.50 per each T-shirt). We want to solve for x when the total revenue and total cost are equal: Total Revenue = Total Cost 12x = 500 + 4.50x 7.50x = 500 x = 500/7.50 = 66.66666... 67 T-shirts c) After breaking even, her total revenue, given by 12x, is found by multiplying 12 by the value of x we just calculated: x 67 Total Revenue = 12x = 12 (67) = $804 (Note that, because we can\'t sell 0.666... of a T-shirt, x is rounded to 67 T-shirts. However, when x = 67, the total revenue actually exceeds the total cost by a bit, so it isn\'t exactly \"breaking even\", but its as close as possible that we can get while still selling an integer number of T-shirts.).

1. In forecasting, explain how you would determine which variable is the independent variable, and which is the dependent variable? 2. Regarding productivity Solution Forecasting can be defined as a method or technique for estimating a business or any operations management. For example, the size of a sales force is likely to have an impact on the total sales for a region. So here, the observed value of totals sales in a region is independent variable while the observed value in sales force in dependent variable. Productivity is the measurement of efficiency with which an economy transforms inputs into outputs. Productivity can be measured in terms of level or growth, eg-GDP. Multifactor Productivity is a ratio of total output to a subset of inputs. All the outputs in a multifactor productivity must be measured in same units, eg-in dollars or standard hours Operations Management is about designing an managing products, processes, services and supply chains. Operations management in the area of product management is concerned with designing, overseeing and controlling production of goods in terms of business requirements. Service Operations management focuses on how firms can deliver excellent service while achieving business goals. A) Products are more different than services and need to be treated differently - is a better option among the two since product operations need to focus on the product design and management while services focuses on the service provided rather than the end product. In a service oriented management, the customer stands important while in product management, the product is given due importance..

1. If yields are unchanged, explain why the price of a coupon bond selling at a discount increases as its maturity date approaches. 2. If yields are unchanged, explain why the price of a coupon bond selling at a premium decreases as its maturity date approaches. Solution If yields are unchanged, the maturity amount is the par value of the bond. So, you can imagine that a bond that sells at a discount, the price of the bond is expected to increase to reach the par value by the time of the maturity. The opposite applies in the case of a bond selling at premium. Again, another way to look at it is that as the time to maturity approaches for a discounted bond, the reinvestment risk decrease and so the value of the bond increases. On the other hand, in the case of abond selling at premium, the benefits of higher coupons approaches its end and so the value of the bond decreases..

1. I know that customers who live in a geographical area (A) purchase an item 75% of the time. 2. I know that customers who have an income (I) purchase an item 60% of the time. 3. I have a customer (C) with the characteristics of (A) and (I). 4. I\'m not aware of any significant correlation or influencing factors between populations (A) and (I), and the data sample for that overlapping is not large enough-- Lets say Customer (C) is the only member of the population with both (A) and (I). How would I determing the liklihood that Customer (C) will purchase an Item? Would averaging the probabilities be appropriate, for (0.6+0.75)/2 = 0.675%? Solution First of all, the problem is not well posed, since the formulation is contradicting. If everyone in A purchases 75% of the time (or with probability 3/4) and everyone with income I purchases 60% of the time (or with probability 3/5), then there can be no overlap, since no single person can buy with two different probabilities (or 75% of the time *and* 60% of the time). Instead, you could consider the following scenario: Let\'s say a new product is on the market. Among the #A people living in A, 75% decide to buy it. Among the #I people with income I, 60% decide to buy it. What fraction of people living in A with income I decide to buy? Let this fraction be P. Let S be the intersection of A and I, i.e., the set of people living in A who have income I. This question assumes that #S>0. While this is a well-posed problem, it is not possible to say much about it, since the answer depends on the relative size of the sets. We can only give ranges: Let A\\I be the set of people in A whose income is not I. Let I\\A be the set of people with income I who don\'t live in A. If the intersection #S is small relative to both #A and #I the answer could be anything from 0% to 100%. Since 75% of the folks in A buy: If #S>#A/4, then P>0. (Even if everyone in A\\I bought, some folks in S need to buy, too.) If #S>#A 3/4, P<1. (Even if everyone in A\\I didn\'t buy, some folks in S didn\'t buy, either.) Since 60% of the folks in I buy: If #S>#I 2/5, P>0. (Even if everyone in I\\A bought, some folks in I need to buy, too.) If #S>#I 3/5, P<1. (Even if everyone in I\\A didn\'t buy, some folks in S didn\'t buy, either.) Now, let\'s generalize this. Let x=#S/#A and y=#S/#I. We can express the feasible region (admissible values for P) as follows: For A: We have the following constraints: P>=0, P<=1, P>=x-1/4, P<=7/4-x. For I: We the constraints: P>=0, P<=1, P>=y-2/5, P<=8/5-y. When you draw theses bounds on P as a function of x and y, you get two pentagonal areas. P has to lie in both of them. If x and y are given, this allows you to find the admissible values of P. You see that for x=1, only P=3/4 is possible. For y=1, only P=3/5 is possible. So x=y=1 is not possible, this would mean that A=I=S, which obviously would violate the assumption. You could ask the question what is the largest (common) value of x and y such that a so.

1. How do correlation coefficients summarize the information in scatter-plot? What do scatter- plots reveal that correlation coefficients do not? 2. What is the relationship between the correlation coefficient and R-squared? Solution 1. They summarise the strength and direction of any potential linear relationship between x and y. 2.In statistics, the coefficient of determination R2 is used in the context of statistical models whose main purpose is the prediction of future outcomes on the basis of other related information. It is the proportion of variability in a data set that is accounted for by the statistical model. It provides a measure of how well future outcomes are likely to be predicted by the model. There are several different definitions of R2 which are only sometimes equivalent. One class of such cases includes that of linear regression. In this case, if an intercept is included then R2 is simply the square of the sample correlation coefficient between the outcomes and their predicted values, or in the case of simple linear regression, between the outcomes and the values of the single regressor being used for prediction. In such cases, the coefficient of determination ranges from 0 to 1. Important cases where the computational definition of R2 can yield negative values, depending on the definition used, arise where the predictions which are being compared to the corresponding outcomes have not been derived from a model-fitting procedure using those data, and where linear regression is conducted without including an intercept..

1. Does materiality change during the course of an audit? 2. Do all qualitative factors mean that an item is material? 3. what areas in a financial statement would draw high attention in a qualitative materialiality factor?-- Solution 1. The determination of materiality is a matter of professional judgment. In determining the materiality of an item, the auditor considers not only the item’s nature and amount relative to the financial statements, but also the needs of financial statement users. Materiality has to be considered before a detailed audit program can be prepared. In the initial planning, however, an auditor cannot anticipate all of the factors that will ultimately influence the materiality judgment in the evaluation of audit results at the completion of the audit. Therefore, these factors must be considered as they arise, and any change in materiality may be incorpoarated throughout the course of audit. No not all qualitative factors mean that an item is material. These areas draw high attention on qualitative materialaity factor. Matters that affect the organization’s social and legal licence to operate or matters that affect the availability, quality and affordability of the capitals the organization uses or affects (e.g. matters affecting reputation and credibility such as regulatory infringements, sensitive factors like fatalities, pollution, unemployment, negative economic effects)..

1. Discuss briefly the various abstractions from precipitation. 2. Discuss the factors affecting the infiltration capacity of an area. 3. With the help of typical hydrographs describe the salient features of: (a) Perennial, (b) Intermittent, (c) Ephemeral streams. Solution The various abstractions from precipitation can be elaborated as :-a) Evaporation b) Transpiration c) Infiltration d) Surface Detention e) Storage..a) Evaporation:- This can be defined as the process by which water is converted from its liquid form to vapor form and thus transferred from land and water masses to the atmosphere.The various factors affecting Evaporation rate are :- Vapor Pressure,Wind,Temperature,Atmospheric Pressure,Soluble Salts,Heat Storage in water bodies. b) Transpiration :- It can be defined as the process by which water leaves the body of a living plant and reaches the atmosphere as water vapor.The water is taken by the plant root system and escapes through the leaves.The various factors affecting it are:- a) atmospheric vapor pressure,temperature,wind,light intensity and characteristics of the plant such as the root and leaf systems.c) Infiltration:- It can be defined as the flow of water into the ground surface such as rainfall,snowmelt and irrigation into the soil. d) Surface Detention :- It is also called detention storage and can be defined as the part of the rain which remains on the ground surface during rain and either runs off or infiltrates after the rain ends. e) Storage/Groundwater Storage:- It can be defined as the water present below the earth\'s surface in soil pore spaces and in the fractures of rock formations.We can define a unit of rock or an unconsolidated deposit as an aquifer when it can yield a usable quantity of water. 2.Infiltration capacity can be defined as the maximum rate at which a given soil at a given time can absorb water .It is expressed in units of cm/hour and is designated as fp(f subscript p).The various factors affecting infiltration capacity of an area are :- a) Characteristics of the soil (texture,porosity and hydraulic conductivity) b) Condition of the soil surface c) Vegetative cover d) Current moisture content e)Soil temperature. 3.Various streams can be classified as Perennial,Intermittent and Empheral on the basis of the study of annual hydrographs of those. A perennial stream can be defined as the one that always carries some flow in it as shown in the figure.It has considerable amount of groundwater flow throughout the year.In this case, even during the dry seasons,the water table will be above the bed of the stream.Whereas the intermittent stream has limited contribution from the groundwater.In this case during the wet season , the water table is above the stream bed and there is contribution of base flow to the stream flow.But during dry seasons the water table drops to a lower level than that of the stream bed and the stream dries up.However excepting for an occasional storm that can produce a short dur.

1. Describe why a manager needs to understand the characteristics and importance of financial markets including risk and efficiency. 2. Describe why cash flows are more important than sales in a business 3. Discuss what could happen if management does not fulfill its financial responsibilities related to the business--dig deeper than just the business will fail. Find an article that highlights a real life example of management making poor financial decisions that affected the business. Solution 1. A manager needs to understand the characteristics and importance of financial markets including risk and efficiency because risk is inseperable from performance. Understanding risk is one of the most important parts of a financial education. We always expect a higher rate of return even if we invest in risky ventures. The investments have a low and negative value in economy and it sometimes creates uncertainity in the financial market. Therefore manager should have understanding about financial markets including risk and efficiency. 2. Csh flows are more important than sales. It gives a picture of the transactions to be classified into Operating Expenses , Investing Activities and Financing Activities. It maintains Company\'s Financial Stability. 3. Management has to fulfill the financial responsibilities related to business for its smooth operations. An example could be when a person starts his new business without inter pretting financial forecast. This would sometimes lead into short run profits and then not work out in long run profits. Thus resulting in decrease of cash flows which will in turn affect business.
