According to initial data of your options:
1) Build a random number distribution, creating 5 groups with equal intervals. Construct the distribution series graphics: histogram, polygon, cumulates.
2) For each group, and together determine the number of units of units and their share in the total number of units (structure). The results of calculations in the present table.
3) According to the group, calculate the characteristics of a number of distribution units: the average level of the series (the formula of average arifemticheskoy conventional method and the method of moments); the scope of variation; the average linear deviation; dispersion (in formulas conventional method and moments); standard deviation; coefficient of variation; fashion and the median for a discrete interval and number of distributions. Analyze the results.
4) With a probability of 0.964 to determine the sampling error average value per unit and the border, which will be in general average.
With a probability of 0.997, determine the sampling error for the proportion of units that are in fifth last interval group number and distribution of the border, which will be the general share. Draw conclusions.

Objective 2. There are reports of average per capita income in Russia in 2010, RUB:
Year Per capita income per capita, rub. / Person.
2006 10000
2007 12315
2008 14826
2009 16739
2010 18565
To analyze the dynamics of the studied index, determine:
1) a) in accordance with the classification - the form of a number of speakers;
b) the average number;
c) The chain and benchmarks for per capita income: absolute increases, the rate (rates) of growth and change;
g) the absolute value of a 1% increment.
2) Average of absolute growth, rates (coefficients) of growth and change.
The calculation results present in table form (table layout):

Make an analysis of the results.
3) a) to identify the linear form of the trend of per capita income of the population;
b) plot the dynamics of the average per capita income over the study period actual and theoretical data;
c) to predict the per capita income in 2013, using the methods:
1) the average absolute growth;
2) the average growth of the theme;
3) analytical alignment.
Make analysis of the results
