1). In a study about postage tariffs and revenue, the European Economic Community wanted to look at the relationship between the number of postal employees in a country and the amount of domestic mail that was processed. They collected data for six different countries and found
Country Number of Staff Domestic Traffic
(Billions of pieces)
Germany 342,413 18.32
France 289,156 23.87
Italy 221,534 6.62
Britain 189,000 16.75
Spain 65,355 4.06
Sweden 52,251 4.21
a) Create a scatter plot of the data and determine whether a linear relationship is appropriate.
b) Find the regression equation for the data.
c) The Netherlands employs 53,560 postal workers. Use the regression equation to predict the domestic mail traffic for the Netherlands.
d) Calculate the values of the residuals for France and Germany.
