A statistical analysis of the data.
For this purpose:
I.
1. Build a statistical distribution number of workers by wage levels, forming 4 groups with equal intervals.
Plot number distribution.
2. Calculate the number of characteristics of the distribution of workers by wage levels: the arithmetic mean, the average linear deviation, variance, coefficient of variation. In calculating the arithmetic mean and standard deviation using the method of moments.
Draw conclusions.
II.
1. With a probability of 0.977, determine the sampling error average wage worker pieceworker and borders, which will be the average salary in the population.
2. With a probability of 0.954, determine the error proportion of workers whose wages exceed 1500 rubles. And the border, which will be the proportion in the population.
Draw conclusions.
