Option 1
Problem 1. There is evidence diameter roundwood (cm):
35 36 37 38 31 32 33 34 35 36
33 32 37 32 34 35 36 37 36 31
32 34 33 35 36 37 36 36 37 34
37 32 36 34 37 33 33 35 34 36
36 33 32 33 35 32 34 32 33 35

Permissible diameter wood for lumber is more than 34 cm.
1. Spread wood into groups with the same diameter in ascending order.
2. Determine the number of logs in each group.
3. Determine how many logs, and which groups will go to the marriage.
4. Results groups present in the form of a statistical table.

Task 2. On the basis of these data on the farming industry:
Gross grain harvest periods, ie. sown area, ha.
Plan fact just t. h. cereals
basic 990 997 695 356
current 1200 1126 861 417

Calculated:
is the relative index of the planned target for the gross grain harvest in the farm;
is the relative index of implementation (execution) of the planned targets for the gross grain harvest in the farm;
is the relative measure of the dynamics of the gross grain harvest in the farm (the plan and the fact);
is the relative index of cropping patterns in the baseline and reporting period;
is the relative measure of the intensity in the baseline and reporting periods.

Problem 3. With probability 0.683 determine boundary of the average weight of packaging coffee beans for the whole party, if the control 10% random inspection gave the following results:
Weight, g
92-96 96-100 100-104 104-108
Number of packages pcs.
30 90 80 20

Task 4. Population 1 January of the year of the Russian Federation for 2002-2009. is as follows:

1. Determine the absolute reduction (chain and basic), the rate of decline (chain and basic), attrition rate (chain and basic) Russian population.
2. Calculate:
-Absolute average annual population decline of the Russian Federation since 2002. by 2009.
is the relative decline in the average annual population of the Russian Federation since 2002. by 2009.
The decision to issue in the table. Draw conclusions.
Problem 5. In the following data, determine the differentiation of the population by income using the Gini coefficients and Lorenz. Draw conclusions.
2009
Money incomes - all 100%
including 20 percent of the population groups:
The first (lowest income) 5.1
A second 9.8
Third 14.8
Fourth 22.5
fifth (highest income) 47.8
