# Description

The task of the theory of probability

Car rental companies are interested in the relationship between the mileage of cars (X) and the cost of monthly maintenance (Y). To clarify the nature of this relationship has been selected 15 cars.

X 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

Y 13 16 15 20 19 21 26 24 30 32 30 35 34 40 39

Plot the data and determine the source of his dependence. Calculate the sample linear correlation coefficient of Pearson, check its value at a = 0.05. Build a regression equation and give the interpretation of the results.
