By letting the GDP (gross domestic product) be the dependent variable (y), and the year (2002 - 2021) be the independent variable (x), answer the following questions: (a) Based on the line graph of the two countries, comment on the significant features from the graphs (identify any unusual points, if any, and observe the trend line). Compare the results of the GDP in these two countries. (Pls refer to the table and line graph in the image attached below) (b) Determine the correlation between the GDP and year, and develop the estimated equation for Ethiopia and Germany. Refer to the summary output of the two countries in the image attached below and interpret the coefficient for the independent variable. Determine whether the regression model is significant at 1% significance level.
