Energy consumption is claimed to be a good predictor of Gross National Product. An economist recorded the energy consumption () and the Gross National Product () for eight countries. The data are shown in the table below: Energy Consumption() 3.4 7.7 12.0 75 Gross National Product() SS i. ii. 58 67 113 131 240 390 1100 1390 1330 1400 1900 Find the least squares equation for the data and Estimate the Gross National Product, X. of a country that has an energy consumption of 100. Estimate the energy consumption of a country that has a Gross National Product of 3500 and Determine at the 5% level of significance whether there is evidence to indicate a linear relationship between energy consumption, and Gross National Product, y Find a 95% confidence interval for 3: and Find the correlation coefficient,

QUESTION THREE Energy consumption is claimed to be a good predictor of Gross National Product. An economist recorded the energy consumption () and the Gross National Product () for eight countries. The data are shown in the table below: Energy Consumption() 3.4 7.7 Gross National Product() i. ii. 111. iv. 12.0 75 55 240 390 1100 58 67 113 131 1390 1330 1400 1900 Find the least squares equation for the data and Estimate the Gross National Product, X. of a country that has an energy consumption of 100. Estimate the energy consumption of a country that has a Gross National Product of 3500 and Determine at the 5% level of significance whether there is evidence to indicate a linear relationship between energy consumption, X., and Gross National Product, y. Find a 95% confidence interval for B and Find the correlation coefficient, Find the coefficient of determination and interpret its value. And Give the ANOVA table for this problem.
