For the period 1990€“1999, the Bristol-Myers Squibb Company, Inc. reported the following amounts (in billions of dollars) for 

(1) Net sales and 

(2) Advertising and product promotion. The data are also in the file XR02062.

For these data, construct a line graph that shows both net sales and expenditures for advertising/product promotion over time. Some would suggest that increases in advertising should be accompanied by increases in sales. Do your line graphs seem to support this?
