Answer and show complete solution.
Data for the energy consumption per person (or per capita) and per capita GNP output for eight different countries are tabulated below:
Country no. | X | Y |
1 | 600 | 1000 |
2 | 2700 | 700 |
3 | 2900 | 1400 |
4 | 4200 | 2000 |
5 | 3100 | 2500 |
6 | 5400 | 2700 |
7 | 8600 | 2500 |
8 | 10300 | 4000 |
In the above table, X = the per capita GNP of each country in 1972 US dollar equivalent and Y = the per capita energy consumption in kilos of coal equivalent
a. Determine the regression equation for predicting the per capita energy consumption on the basis of a country’s per capita GNP output, and graph the regression line.
b. Determine the
c. Evaluate the conditional standard deviation / standard error of estimate.
d. Determine the 95% confidence interval of the regression line by computing confidence intervals on various mean responses. Show a graph of the confidence interval.
