Task 1
The available data on the production of the same product in three workers (tab. 5). Determine the average time per unit of production.
Table 5
Initial data
Working Time spent per unit of production, min. The amount of output, pcs.
Ivanov PI 48800

Task 2
In order to study the yield of sunflower in the field of collective held a 5% sample survey of 100 hectares of crops, selected at random, which resulted in the following data (tab. 6).
1. On the basis of these data, calculate: the average yield from 1 ha of sunflower, variance, standard deviation and coefficient of variation.
2. With a probability of 0.997, determine:
a) limiting the average sampling error and possible limits within which expected average yield of sunflower in the field
b) border, where the proportion of crops is expected in the population with a yield of not less than 17 kg / ha
Activity 3
Mining and production of gas in the region is characterized by the following data (Table. 1). To analyze the extraction and production of gas in the region over the period 1995-2000. The absolute increase, growth rates and rates of growth over the years and by 1995, the value of one percent growth. These figures present in the table. Find the average number of annual average absolute increase, the average annual rate of growth and change for the period 1995-2000. and 1990-1995 years.
Task 4
