Description

Option 4.
Objective 1.
There are reports of 10 companies based on the cost (monetary units) per unit of output by labor input per unit of output (people -chas):
№ p / p 1 2 3 4 5 6 7 8 9 10
X 10,3 11,2 12,3 11,8 14,6 15,8 15,2 14,2 13,1 10,8
Y 110 125 130 131 150 172 158 145 140 118

1. Estimate the coefficients of linear regression by least squares method.
2. Check the statistical significance of the theoretical estimates of the coefficients of the level of significance.
3. Calculate the 95% confidence intervals for the theoretical regression coefficients.
4. Predict in the cost of labor input and calculate the 95% confidence interval for the conditional expectation.
5. Calculate the limit of the range, which will focus at least 95% of the possible consumption volumes on revenues.
6. Estimate how much the cost of change if the complexity will increase by 1 per hour.
7. Calculate the coefficient of determination.
8. Calculate - Statistics for the coefficient of determination and evaluate its statistical significance.
Objective 2.
It is expected that the volume of supply for a good functioning of the company in a competitive environment depends linearly on the prices of goods and wages of the employees of the firm producing this good:
.

1. Assess the least squares regression equation coefficients.
2. Check the quality of the constructed model based -Statistics and - statistics.
Objective 3
When calculating the coefficients of the regression error was made in determining the coefficient (the coefficient is calculated correctly). This yielded. The amount of residue was found to be. Determine the ratio.
Task 4
The correlation coefficient between the variables and is 0.9. What will be the coefficient of determination in the case of a linear regression model?
