ASSIGNMENT 1

Question 1

Table 1 shows the financial ratios for two different groups of firms; the most-admired firms (1) and the least-admired firms (2). The financial ratios are earnings before interest and taxes to total assets (EBITASS), return on total capital (ROTC), return on equity (ROE), return on assets (REASS) and market to book value (MKTBOOK).

## Case Approach

#### Scientific Methodology

We use best scientific approach to solve case study as recommended and designed by best professors and experts in the World. The approach followed by our experts are given below:

Defining Problem

The first step in solving any case study analysis is to define its problem carefully. In order to do this step, our experts read the case two three times so as to define problem carefully and accurately. This step acts as a base and help in building the structure in next steps.

Structure Definition

The second step is to define structure to solve the case. Different cases has different requirements and so as the structure. Our experts understand this and follow student;s university guidelines to come out with best structure so that student will receive best mark for the same.

Research and Analysis

This is the most important step which actually defines the strength of any case analysis. In order to provide best case analysis, our experts not only refer case materials but also outside materials if required to come out with best analysis for the case.

Conclusion & Recommendations

A weak conclusion or recommendations spoil the entire case analysis. Our expert know this and always provide good chunks of volume for this part so that instructors will see the effort put by students in arriving at solution so as to provide best mark.

Question 2

A Sample of 15 houses with similar square footage built by a particular housing developer throughout United States is selected and the heating oil consumption during the month of January is determined. It is believed that the average daily atmospheric temperature as measured in degrees Fahrenheit outside the house during that month and the amount of insulation as measured in inches in the attic of the house influence the heating oil consumption. The data is shown in Table 2.

Table 2 : Monthly heating oil consumption, atmospheric temperature and amount of attic insulation for random sample of 15 single-family houses.

Question 3

A market analyst is interested in determining if type of firms (Most-Admired and Least- Admired) has an effect on the financial ratios (EBITASS and ROTC). The data is tabulated in Table 2. Use MANOVA to achieve the above objective. Interpret the result.

Question 4

The internal Revenue Service (IRS) is trying to estimate the monthly amount of unpaid taxes discovered by its auditing division. In the past, the IRS estimated this figure on the basis of the expected number of field-audit labour hours. In recent years, however, field-audit labour hours have become an erratic predictor of the actual unpaid taxes. As a result, IRS is looking for another factor with which it can improve the estimating equation. The auditing division does keep a record of the number of hours its computers are used to detect unpaid taxes. By using data in Table 3: Technique – Multiple Linear Regression

1. Fit a more accurate estimating model for the unpaid taxes discovered for each month.
2. Determine the significance of each predictor.
3. Find and interpret the Coefficient of Determination.
4. How much in unpaid taxes do they expect to discover in November?
