Question: 4. Solve the problem: (6,0) Using the following values: sum squared of deviations on variable X equals 60, sum squared of deviations on variable Y

4. Solve the problem: (6,0) Using the following values: sum squared of deviations on variable X equals 60, sum squared of deviations on variable Y equals 20; sum of product of deviations between the variables X and Y equals 30; arithmetic mean for variable X equals 4, arithmetic mean for variable Y equals 10. Number of observations 18. X pr=2 Estimate the coefficients: intercept and slope. Compute the table ANOVA and determine the coefficient of determination. Calculate the standard error on the estimated equation. Make the tests on statistical significance for level of significance 0,05 (t-test, F-test). List all levels of significance for which the null hypothesis is rejected. Calculate the pointed forecasting and confidence intervals. Calculate the average coefficient of elasticity; interpretation. Write a general conclusion about the quality of fitting the estimated equation
