James Trucking is studying the relationship between the distance a shipment must travel and the length of time, in days, it takes the shipment to arrive at its destination. To investigate, Mr. James, the manager of the company selected a random sample of 20 shipments made last month. Shipping distance is the independent variable, and shipping time is the dependent variable. The results are as follows: Shipment Distance (miles) Shipping Time (days) 1 656 5 2 853 14 3 646 6 4 783 11 5 610 8 6 841 10 7 785 9 8 639 9 9 762 10 10 762 9 11 862 7 12 679 5 13 835 13 14 607 3 15 665 8 16 647 7 17 685 10 18 720 8 19 652 6 20 828 10 Is the relationship between shipping distance and shipping time significant, if the level of significance is 5%?
