Bardi Trucking Co., located in Cleveland, Ohio, makes deliveriesin the Great Lakes region, the Southeast, and the Northeast. JimBardi, the president, is studying the relationship between thedistance a shipment must travel and the length of time, in days, ittakes the shipment to arrive at its destination. To investigate,Mr. Bardi selected a random sample of 20 shipments made last month.Shipping distance is the independent variable and shipping time isthe dependent variable. The results are as follows:
Shipment | Distance (miles) | Shipping Time (days) | Shipment | Distance (miles) | Shipping Time (days) |
1 | | 782 | 14 | | 11 | 609 | 10 | |
2 | | 724 | 15 | | 12 | 855 | 10 | |
3 | | 616 | 15 | | 13 | 687 | 9 | |
4 | | 751 | 11 | | 14 | 663 | 12 | |
5 | | 713 | 5 | | 15 | 687 | 9 | |
6 | | 800 | 3 | | 16 | 845 | 12 | |
7 | | 726 | 9 | | 17 | 615 | 10 | |
8 | | 831 | 14 | | 18 | 789 | 7 | |
9 | | 649 | 6 | | 19 | 744 | 5 | |
10 | | 824 | 6 | | 20 | 706 | 5 | |
