The paper offers two studies: first, it calculates the total firm value of DCom at the end of year 2000 using the free cash flows to the firm (FCFF) model, and arguing whether this value is appropriate to assess the value that DCom should contribute to the market price of Jones Group equity. The limitations of two-stage DDM and FCFE models are identified and compared. Second, the paper estimates the regression equation proceeding from the data on real gross product, labour input and real capital input in the engineering sector for the years 1992-2006.

The data on the attendance to the flea-market is studied. The initial set includes the monthly averaged number of dealers inside, dealers outside, and consumers during two years. The linear trend is fitted to the data and then the multiplicative and additive models are built to forecast the evolution of these numbers for the next three years. The time when the number of dealers and visitors reach the particular levels is predicted. Reliability of the forecast is assessed which in our particular case is low due to the insufficient data.

A statistical dataset on 30 customers of a supermarket is made up using MS Excel random function. The dataset includes weekly expenditure, perception of the supermarket expensiveness, time spent at the check-out, and the time spent driving to the supermarket. A matrix is composed from the data to be used in linear regression model. Regression coefficients are calculated first as the solution of the corresponding matrix equation and then using Eviews and MS Excel. All three ways of calculation give the same result as expected. Consumer loyality is tested by testing the independence of expenditure and the price perception. The effect of driving time on the expenditure is assessed.

A statistical survey on the variety and the pricing of the second hand cars sold by the local car dealers is performed. Data is acquired from the autotrader.co.uk internet database. A set of 75 cars of 3 brands, not older than 5 years, is analyzed using the MS Excel. Descriptive statistical values are calculated and interpreted; some frequency distributions and statistical observations on the car colour, engine size, and CD-player accessory are presented. A question is formulated concerning the difference in the average price of cars sold by different dealers. A simple investigation is undertaken to show that the price difference is defined by the choice of cars but not by the pricing policy of the traders. A critical appraisal of the survey is performed. MS Excel file with the pivot table and a variety of graphs and histograms is attached.

The paper provides answers on the following questions:
1. Outline the concepts of simple probability, conditional probability and joint probability, illustrating your answer with examples.
2. What are Type 1 and Type 2 errors? How are they related?
3. Write down the general form of the linear equation used in multiple regression and explain what multiple regression is used for. Why is the term 'least squares' sometimes used to describe the method?
4. The chi-squared test of the independence of two variables is commonly used to analyse contingency tables. Outline the assumptions underlying the test and explain how the test uses the difference between observed and expected values.
5. Height and weight are positively correlated in human populations. Explain the concept of correlation and describe the characteristics of Pearson's r.
6. The descriptive statistics calculated for a data set commonly include measures of central tendency and dispersion. Explain these two types of statistics illustrating your answer with examples.
7. What conditions are required for a sample to be representative of a population? Why is representative sampling important but hard to achieve?
8. The F-statistic, which is used in the analysis of variance (ANOVA), is a ratio of two quantities. Explain what the two quantities are and how they relate to between and within groups variability.
9. Explain the relationship between a region of rejection and a critical value of a test statistic.
10. A hierarchical cluster analysis is based on the "distance" between pairs of items. Explain the concept of distance giving examples of ways in which it can be measured. Page 2>
