1. Calculate the average price of goods on the implementation of the two points in the 3rd and 4th quarters. Specify the type of medium used by, compare the results.
2. To determine the effect of price changes on sales of goods for each point separately and implementation of both together. Draw conclusions.

Cost and volume of identical products of the two firms is as follows:
Companies Products 2010 2011
The volume of production, thous. Pcs. Cost of 1 pcs., Rubles. The volume of production, thous. Pcs. Cost of 1 pcs., Rubles.

Estimate:
1. For each of the firms in the context of the entire range of output and its individual components of the index the cost of production, volume production, the cost of production.
2. For the two companies, along with product index dynamics of the average cost, the cost of constant composition index, the index of structural change.
3. To analyze the results in terms of determining the state of the market environment.

Objective 3
According to the company are the following:
Goods Reported production costs of goods, thous. Changes in the unit cost of goods%

On the basis of these data to determine: the average change in the cost of production; the absolute amount of savings and cost overruns on changes in unit costs. Draw conclusions.

In the reporting year 25 companies sub-sector is characterized by the following data on the average annual value of fixed assets (mln. Rub.) And the cost of salable production (mln. Rub.):

On the basis of the data relevant to your version, run:
1. Build a structural grouping of value of fixed assets using the equal-closed intervals, taking the number of groups is 4.
2. On the basis of the structural groups to build a frequency variation and a cumulative series. The results are presented in a table and graphically.
3. To analyze the variation number distribution by calculating:
 the arithmetic mean value of the sign;
 mode, median, 1st quartile, 3rd and 9th decile;
 standard deviation;
 the coefficient of variation.
4. To draw conclusions.

Objective 5
The dynamic range of the number of births in some areas in 2000-2006. characterized by the following data:
Option 4:
Years 2000 2001 2002 2003 2004 2005 2006
Births, thous. People. 3 265 3 561 3 347 3 398 4 213 4 221 4 202
On the basis of the number of speakers to determine:
 absolute increases, the rate of growth and change over the years and by 2000, the absolute content of one percent increase (obtained figures represented in table form);
 the annual average number of births and the average annual value growth of this number;
 an average annual rate of growth and change during the period;
 to produce a number of smoothing a three-year moving average of the dynamics;
 graphically (in a coordination plane) and the actual aligned rows;
 draw conclusions.
