The data in Table 1 reports the aggregate consumption (Y, in billions) and disposable income (X, in billions) for the prosperous land of Kumandra. Draw a scatter diagram for the data and determine by inspection if there exists an approximate linear relationship between Y and X. Approximately draw a straight-line between the plotted values.  Can we use this data for a linear regression model? Why?
