You are writing a paper for your Quantitative Analysis class and have come across the following information that you will include in your paper as your second graph. The information is concerning high end auto tire sales in Canada from 2016-2021. Quantity (Q) is measured in tens of thousands of tires sold and Price (P) is the price of each tire measured in tens of Canadian dollars. The Wall Street Journal article that included the data was entitled "Selling Canadian Tires." The article was written by Bruce Rennert and was published on pages 111-112 in the June 14, 2022, hard copy edition of the paper. The data is below:
